[Non Returnable] 5422 Henry Packless Relief Valve By-Pass 5/8" ODS Inlet x 5/8" ODS Outlet

Packless valves are so called due to the absence of a packed gland for stem sealing. Instead, metal diaphragms are used to isolate the stem from the fluid area.

Applications:

Henry Technologies packless valves are used in a variety of air conditioning and refrigeration applications for isolating, flow control, charging and purging purposes. The valves are suitable for HCFC and HFC refrigerants, along with their associated oils. The 2100B & 2111B series are suitable for HCFC, HFC and CO₂ refrigerants along with their associated oils.

Main Features:

• Robust design

• Heat stabilised nylon seat ring for positive shut-off
• Positive back-seating with valve in open position
• Raised seat reduces debris induced sealing issues
• Large diameter diaphragm for greater lift, better flow and longer life
• Hermetic seal between bonnet, diaphragms and body
• Suitable for vacuum applications
