Cryogenic Safety Relief Valves
*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.
Parker Bestobell’s cryogenic safety relief valves are designed to protect cryogenic static and road-going storage tanks or capital equipment from damage caused by over-pressure.
These cryogenic safety relief valves feature an innovative proportional lift action which ensures that when the pressure in a tank rises, the safety relief valve activates and releases pressure gently to enable it to drop back to a safe pressure.
They are available in three basic sizes defined by the throat diameter and are available with a variety of inlet and outlet connections. The valves are designed and factory set to lift repeatedly within +/- 2% of the set pressure and to re-seat above 92% of set pressure. Spring pre-compression and blow-down ring settings are securely sealed and factory set after testing to inhibit unauthorised tampering, as these are Category Four safety products. Flow rates at 10% above set pressure are measured to ensure compliance with stated flow capacities as an additional safety precaution.
These valves have an exceptional safety record in the field and have been used on a worldwide basis for over 50 years.
Markets:
Industrial Gas – designed and engineered for use with Group 1 gases
Features/benefits:
• Unique proportional lift action to release pressure gently
• Manufactured from high quality Stainless Steel or Bronze
• Designed to comply with ISO 4126 (Safety Valves General Requirement), Ad-Merkblatt A2 (Safety Devices against Excess Pressure) and TUV requirements.
