Description

Circle Seal Controls Model HP562T1-4MP Relief Valve

Catalog literature: Relief Valves Catalog.pdf

The Circle Seal Controls model HP562T1-4MP Relief Valve is a small, durable valve for use on pressure lines and pressure vessels of all types. It is bubble-tight at normal operating pressure, cracks accurately and repeatedly at a preset pressure to pass adequate flow with minimal pressure rise. It offers exceptional performance characteristics in service with virtually all gases and liquids.

Features:

• Zero leakage: up to 95-98% of cracking pressure
• Increased sealing efficiency: as pressure increases, the resilient o-ring seal is forced against the metal poppet up to the cracking pressure
• Cracking pressure accuracy: valves can be pre-set to required cracking pressure; 100% seat leakage tested
• Tamper-proof adjustment: adjustable only from the inlet side for safety against tampering; permits precise setting for the most exacting system requirements
• Sticking eliminated: poppet head provides metal seat on the low pressure side of the seal, which limits squeeze on the resilient o-ring; prevents water and dirt from entering the valve
• Long, maintenance-free service: parts will not wear out in normal service; overhaul, if necessary, is quickly made by replacing the resilient o-ring seal
• Variations: vent-to-atmosphere or inline connections; various materials for both the body and seals; PED certifications and CE marking available for most models

Applications:

• System overpressure protection
• Storage tanks
• Freon recovery systems
