Cryogenic Safety Relief Valves CWF40YV19

Parker Bestobell's cryogenic safety relief valves are suited to the protection of static and road going cryogenic storage tanks against damaging over pressure.

A range of high quality Stainless Steel and Bronze relief valves designed to comply with ISO 4126 (Safety Valves General Requirement), Ad-Merkblatt A2 (Safety Devices against Excess Pressure) and TUV requirements. They are eminently suited to the protection of static and road going cryogenic storage tanks against damaging over pressure.
There are three basic sizes, defined by the throat diameter and each is available with a variety of inlet and outlet connections.
The valve is designed and factory set to lift repeatedly within 2% of the set pressure and to reseat above 92% of set pressure. Spring pre-compression and blow down ring settings are sealed after test to inhibit unauthorized tampering.
Flow rates at 10% above set pressure.
All valves are degreased for oxygen duty, assembled in clean room conditions and sealed in robust polythene bags prior to dispatch.
Each valve is individually set and flow tested and then stamped with the date of manufacture and its own unique serial number prior to dispatch.
