Parker PA4

The Parker PA4 Pressure regulator weld-in line valves are designed to overcome corrosion problems encountered in harsh environments. Being weld-in, the valves reduce potential for connection leaks and can be entirely serviced from the top. This improved design has a higher working pressure, temperature range and flow capacities than flanged products.

PA4 features:

• Cartridge based design simplifies service
• Increased flow capacity enables smaller valve sizing
• Overall weigh reduction up to 50% compared to traditional flanged products
• Integral features prevent contaminants from reaching the pilot section of the valve
• Suitable for ammonia, CO2 and halocarbon refrigerants
• Supplied factory assembled and tested
