Long Stem Globe Valve

Extended Bonnet Cryogenic Globe Valves - BK and BKA Series Valves

Application:
The BK and BKA Series valves are designed exclusively for the handing of cryogenic liquids on bulk storage tanks, transports, and pipelines. These globe valves provide positive shutoff and offer a long, low-maintenance service life. The valves are available with a variety of inlet and outlet connections and stem lengths. Certain BK valves are offered with brazed-in Sch5 Stainless Steel Pipe Stubs.

Features:
* CTFE seat disc and swivel seat design offer positive shut-off, minimal sea wear, and a long service life.
* Unique spring-loaded upper packing provides extended service life without constant packing adjustment.
* One piece slip-on seat assembly for easy replacement.
* Each valve is pressure tested to be leak free.
* Each valve is cleaned and packaged for oxygen service per CGA G-4.1.
* Maximum working pressure is 600 psig CWP.
* Working temperature range is -32 0℉ to + 165 ℉.

Bonnet Design:
Union Bonnet for 1/ 2” , 3/ 4” , 1” valve sizes and on both the 1” model BKA8408S and 1 1/ 2” model BKA8412S angle valves. Bolted bonnet design is used on the BK9410, BK9412, and BK9416 models.

Extended Stem Cryogenic Valves - ES8450 Series Extended Stem Valves, BK9450 & BK9470 Series Extended Bonnet Valves

Application:
These valves are designed for use as trycock valve or hose drain valve on cryogenic tanks. Another application is as a use, liquid fill, or vent valve on mini-bulk cryogenic tanks. These valves can be used likewise for other cold gas applications requiring extended stem valves.

Features:
* Union bonnet.
* One piece stainless steel stem.
* Conical seat design.
* Maximum working pressure is 600 psig.
* Working temperature is -320℉ to + 165℉.
* Cleaned for oxygen service per CGA G-4.1.

Short Stem Globe Valve

9450 Series & 9460 Series

Application:
The 9450 and 9460 series valves are designed for use on portable cryogenic cylinders and other in-line shut-off valve applications.

* Spring loaded stem seal automatically adjusts for any gasket wear, eliminating the need to constantly retighten the packing nut.
* Non-rising stem and low profile allow the valve to fit into tight areas and still provide easy access.
* Unique pressure-sealed moisture barrier helps prevent freeze up at cryogenic temperatures.
* Conical swivel seal design helps prevent seat galling from over torquing.
* Cleaned for liquid oxygen service per CGA G-4.1.
* Maximum working pressure is 600 PSIG.
* Working temperature range is -320℉  to + 165℉ .

Extended Stem Retrofit Kits

Application:
These retrofit kits can be used to convert the 9450 and 9460 series short stem shut off valves into extended stem style. The conversion can be done without removing the valve from your system. Available in to two stem lengths. All kits are oxygen cleaned and packaged per CGA G-4.1.

Cryogenic Regulators

RG Series

Application:
The RG series cryogenic regulators are primarily designed to maintain pressure on cryogenic liquid within cryogenic containers. They may also be used in cryogenic lines, vaporizer and converter applications. They are especially useful in installations where space and cost limitations are important.

Features:
* All parts are copper alloy (brass), PTFE and stainless steel — materials selected specifically for compatibility with cryogenic temperatures down to -320℉.
* Body and bonnet machined from soild brass bar stock.
* PTFE seat helps assure a positive shut-off at cryogenic temperatures down to -320℉ .
* High and low pressure regulators are the same compact size — designed to fit in close quarters. The compact high pressure design has no loss of flow capacity.
* Interchangeable with existing cryogenic regulator units.
* Inlet filter helps prevent foreign material from entering the regulator.
* Locknut is provided to maintain adjusting screw setting.
* Maximum inlet pressure of 550 PSIG.
* Cleaned for liquid oxygen service per GCA G-4.1.

Cryogenic Economizers

ECL Series

Application:
The ECL series cryogenic economizers are primarily designed to utilize the gas pressure in a liquid cryogenic cylinder that would otherwise be lost to the atmosphere through the pressure relief valve. They may also be used in cryogenic lines, vaporizer and converter applications. They are especially useful in installations where space and cost limitations are important.

Features:
* All parts are copper alloy (brass), PTFE and stainless steel — materials selected specifically for compatibility with cryogenic temperatures down to -320℉.
* Body and bonnet machined from solid brass bar stock.
* The ECL Series utilizes a stainless steel needle seat design that provides a very sensitive flow control at lower pressure settings.
* High and low pressure economizers are the same compact size — designed to fit in close quarters. The compact high pressure design has no loss of capacity.
* Interchangeable with existing cryogenic economizer units.
* Inlet filter helps prevent foreign materials from entering the economizer.
* Locknut is provided to maintain adjusting screw settings.
* Maximum inlet pressure of 550 PSIG.

Cleaned for liquid oxygen service per CGA G4.1.
