Refrigeration Valves

We  offer varieties of refrigeration valves used are designed for either liquid or suction line application. They provide free flow with negligible pressure drop and can be used for a variety of liquids.

 We offer following range of products :

• Stop valves weld in line, SBW,
• Stop Valves FSV,SSV
• Electronic Liquid Level Controller
• Float Switch
• Solenoid valves
• Digital Temperature Indicator.

Type : SEV 
    

• Port Size : ¼” thru 1” (6mm – 25mm) for globe and angle form, screwed end.
• ½” thru 2” (15mm – 50mm) for globe and angle form, flanged end.

SUPERFREEZE SEV Series precision calibrated adjustable seat nut flow regulating valves (expansion valves) are ideal for metering or flashing expansion of liquid refrigerant. These slotted seat nut are more tolerant to dirt particle than tapered plug expansion. Hand wheels are of red color to distinguish them from shut-off valves.

Applications:

• Liquid feed or circulating liquid over feed evaporators.
• High pressure or intermediate pressure liquid feed to accumulators, intercoolers or recirculators.
• Defrost condensate relief.
• Suitable for R-717 (Ammonia), Halocarbons

Type : SRV

SUPERFREEZE SRV-Series pressure relief valves are designed to provide emergency relief from excessive pressure in refrigerant containing vessels. These tamper-resistant valves are accurately set and sealed by qualified technicians at the factory.
Our safety valve design features the most reliable method of safely relieving pressure. The virgin Teflon seal mated with the stainless steel multiple crown ring, provide an outstanding sealing action, The combination assures a non-stick and accurate pop-off pressure release. The design incorporates special extra lift, pop-open feature for high relieving capacity.

Specifications:

• Safe working pressure     : 365 psig (25 bar)
• Maximum Temperature rating     : 116oC (240`F)
• Setting Range     : 150 to 350 psig (10.4 to 24 bar)

Applications:

Pressure relief valves helps meet the requirements of ANSI/ASHRAE 15-1997 SAFETY CODE FOR Mechanical Refrigeration as well as other world wide codes. This code requires pressure vessels of all refrigeration systems to be protected by a pressure relief device or other approved means to safely relieve pressure in the event of fire or other abnormal conditions. Once installed, is ready to vent to atmosphere any temporary excessive overpressure inside of a vessel. After discharge, these valves will attempt to reseat to minimize loss of refrigerant.

Standard Sizes:

• Cat No.     Size     Inlet     Outlet
• SRV 1520     15mm X 20mm     ½” FPT     ½” FPT
• SRV 1525     15mm X 25mm     ½” FPT     1” FPT
• SRV 2025     20mm X 25mm     3/4” FPT     3/4” FPT
• SRV 2532     25mm X 32mm     1” FPT     1 1/4” FPT

Other sizes can be supplied upon special request.

Type : SDM

SUPERFREEZE SDM-Series In accordance with ANSI/ASHRAE 15-1994 Safety code for mechanical Refrigeration, pressure vessels having 10 cubic feet or more of internal gross volume, shall be fitted with dual pressure relief valves. This is typically accomplished using a pair of pressure relief valves inter connected via a three way dual Manifold. In this one valve remains operational, while the other is being replaced there by eliminating the need to remove refrigerant from the vessel.

Applications:

These valves facilitate the parallel installation of pressure relief valves. Because three way valves will not isolate both pressures relief valves simultaneously, they are considered the only acceptable type of shut-off valve for use with refrigerant relief piping. Inlet and out let connections are threaded female.The valve stem should be positioned so that only one Pressure relief valve is activated. While the valve can be either front-seated or back-seated, the back-seated position is recommended for normal use because it takes pressure off the packing and reduces the possibility of packing leak.

Advantages:

• Higher releasing capacity
• No isolation valve required, which give more safety to the       pressure vessel with at least one relief valve in  operation.
• One valve can be removed for repairs at any time.

We  offer varieties of Ammonia valves used are designed for either liquid or suction line application. They provide free flow with negligible pressure drop and can be used for a variety of liquids.
