ACTUATORS - With Factory Premounted Valve / Safety Tested and Rated to Conform to ETL, CSA Specifications |
||
| All of our valves are available premounted on compact Electronic Actuators to automate valve positioning. Our valves are coupled with a DC gear motor, which offers outstanding rotational accuracy and low actuation times. | ||
| Upchurch Scientific actuated valves can be conveniently operated by keypad or computer controlled through contact closure and RS-232 communication. LED indicators on the actuator keypad specify valve position. Additionally, valves may be multiplexed (daisy-chained) for custom automation solutions when using RS-232 communication |
DC Gear Motor Actuated Valves |
Each actuator is provided with an inline power adapter which allows operation from both 110/1 20V (North American) and 220/240V (European) AC power. All actuators come with a one-year parts and labor warranty. |

INTRODUCTION - Injection and Selection Valves for Pressures to 1,000 psi (69 bar) / Switching and Shut-Off Valves for Pressures to 500 psi (34 bar) / Directly Connect 1/16" or 1/8" OD Tubing with Fangeless Fittings / Manual and Actuated Versions
|
| Uphurch
Scientific® Medium Pressure Valves are available for 1/16" or
1/8" OD tubing in sample injection or six-way flow selection versions.
These valves have completely biocompatible flow paths and are perfect for
systems where the pressure does not exceed 500 - 1,000 psi (34 - 69 bar),
including flow injection analysis (FIA) and some chromatography
applications. These valves come in manual (with or without a bulkhead
mounting option) and electronically actuated versions. The Medium Pressure Valve series also includes our Switching Valves (rated to500 psi, 34 bar) which offer several options for directional flow control. The most popular is the "L" style - a two-way switching valve that could be used for mobile phase, column or detector selection between two inlets or outlets. Use the "T" style valve with a plug to change a three-way open connection to a two-way selection valve. The "D" style valve is a two position four-way switching valve where adjacent ports are connected by a flow path which rotates 90° to change position. Applications for this valve include protection of column or other sensitive instrument components during a cleaning cycle. These biocompatible four-port switching valves are available for manual control or mounted onto an electronic actuator. Polymer inline shut-off valves are also available for 1/8" or 1/16" OD tubing to quickly turn a flow stream "on" or "off". |

This injection port adapter is adjustable, so you can create a snug fit around the needle to prevent any leaking of the analyte. In addition, this product features an internal stop that prevents you from inserting the needle too far, eliminating the possibility of damaging the valve with the needle tip. |

PRESSURE 4-PORT SWITCHING VALVES - Three Configurations to Choose From / Biocompatible Flow Paths |
|
 |
With three versions to choose from, Upchurch Scientific® Switching Valves offer many flow distribution combinations. Each valve has a low swept volume, can withstand pressures to 500 psi (34 bar), is chemically inert and biocompatible. The PEEKTM and TeflonTM construction results in a valve as durable as it is economical. Each V-100 Series Switching Valve has .040" thru-holes and is supplied with Flangeless Fittings for use with 1/16" OD tubing. To use these valves with 1/8" OD tubing, simply replace the supplied fittings with 1/4-28 Flangeless Fittings. You may notice a slight back pressure at higher flow rates, due to the .040" thru-holes in these valves. To operate, all ports must be either connected to a line of your system or plugged. Built-in positioning detents allow these valves to snap into place, ensuring the thru-hole is properly aligned. |
| Standard
manual valves (V-100D, V-100L- and V100T) measure 1.80" (45.7 mm)
in length. Bulkhead versions (V-101 D, V-101 L and V-101 T) are 2.18"
(55.4 mm) long. The bulkhead mountable manual configuration can also be mounted on our M-615-1 Valve Bracket (see below). DC gear motor actuated versions are also available. Selected applications for our Medium Pressure Switching Valves are listed on the following page. However, there are also several other possible uses for these valves. |

MICRO-SPLITTER
VALVES - For Interfacing LC-MS Systems / Split Stream Flow Rates as Low as 2µl/min. / Medium and High Pressure Versions |
|||||
| MICRO-SPLITTER VALVE INFORMATION | Upchurch
Scientific® offers a line of Micro-Splitter Needle Valves designed to
accurately split and control a low-flow stream off a single incoming
supply. The biocompatible Medium Pressure Micro-Splitter Valves are perfect for LC-MS and other multidetector systems, and fraction collectors. The ideal placement of these valves is on the effluent side of the detector flow cell, at a maximum pressure of 800 psi (55 bar). Choose between 1/4-28 and 10-32 threaded versions. A valve is also available to accommodate applications involving capillary tubing.(1) The High Pressure Micro-Splitter Valves are designed to operate under pressures up to 4,000 psi (276 bar). These products are well suited for running two analytical devices in parallel. The High Pressure Capillary Micro-Splitter Valves (1) may also be used to adapt an analytical HPLC system to handle microbore applications. Our Graduated Valves offer many of the benefits and features of our original Micro-Splitter Valves, plus the ability to adjust and set the split flow to repeatable settings. This allows documentation of settings and the resulting flow rates for easier method development. The graduations also make it easier to employ the valve in a system used to run multiple analyses that require different split flow rates. Choose from regular High Pressure and Capillary (1) versions. All Micro-Splitter Valves have been tested at flow rates to 100ml/min., with a maximum resulting pressure drop of only 45 psi (3.1 bar). (2) (1)This valve has a MicroTight ` 6-32 threaded fitting on the split stream Select the appropriately sized Micro Tight Tubing Sleeve to connect your capillary tubing.

UNIVERSAL
PRIME/PURGE VALVES For Any Style HPLC System / Automatic Luer Syringe Operation / Featuring Handy Mounting Holes |
||
| The
Upchurch Scientific® Prime/Purge Valve for Waters pumps automatically
opens when a luer syringe is attached and closes when the syringe is
removed. No valve rotation is required after the initial installation, so
wear on the internal seal is eliminated. In addition, our Waters-compatible Prime/Purge Valve is simpler to operate and more economically priced than alternative valves available for Waters systems. This valve is constructed of rugged materials, including a PEEK™ valve body. The component structure ensures compatibility with virtually all common solvents used in HPLC analyses. A Waters-compatible internal Teflon® seal is included with the valve. This seal can also be purchased separately. It can be used both with the Upchurch Scientific valve and the original valve supplied with the pump. |
|
Upchurch
Scientific Universal Prime/Purge Valves are easy to operate. Simply
install a valve along the flow path with the included fittings and attach a luer-tipped syringe. Then, withdraw the plunger and watch as solvent and residual bubbles are removed from the solvent line. The valves automatically close when the syringe is removed. The low pressure version of the valve is designed to be used with 1/8" OD tubing, while the high pressure version accommodates 1/16" OD tubing. Optional mounting is made easy by the handy holes in the body of each unit. |
|
| Air in the
Pumphead Air within the pumphead can cause flow instability and noisy pump operation. Place the High Pressure Prime/Purge Valve between the pump and the sample injector, where it can be used to remove bubbles that have become lodged within your pump. This valve is rated for a maximum pressure of 5,000 psi (345 bar). |
|||
 |
Air
in the Inlet Solvent Line Install the Low Pressure Universal Prime/Purge Valve along the inlet solvent path near the pump to remove bubbles from the inlet solvent line. The valve can also be used to rapidly "wet" your solvent inlet filter. When a new filter is installed, it often contains a substantial amount of air within its pores. At standard flow rates, it may require several minutes before the inlet fluid pathway is completely free of gas. Using this valve, you are able to rapidly draw solvent through the inlet filter, dislodging the gas and minimizing downtime. |
