Cartridge Safety Relief Valve (CSR & CSRH)

Description

• Streamline high capacity cartridge safety relief valve (CSRH)
• Suitable for ammonia and halocarbon refrigerants
• Stainless steel cartridge and internal components

Basic Specifications

• Temperature range -40°C to 150°C (-40°F to 300°F)
• Available in six pressure setting ranges 10.3 to 27.6 (150 to 400 psig)
• ±3% set pressure tolerance
• ASME Boiler and Pressure Vessel Code compliant
• ANSI/ASHRAE 15 safety standard for refrigeration systems
• Same lay in length as SR and SRH series safety relief valves
• Cartridge based design allows for replacement while housing remains in the system
• Limits pressure from rising more than 10% above designed working pressure (DWP) or pressure setting of relief device
• Non-stick PTFE seat
• Designed to offer the highest level of protection

Models

• CSR1: Connections from 13-20mm (½-¾ inch)
• CSR2: Connections from 13-25mm (½-1 inch)
