Construction

• Machined components are manufactured using solid bar stock
• Stainless steel balls, retaining rings and springs maximize corrosion resistance and extend service life.
• Steel componentry is plated using ROHS compliant zinc nickel for corrosion resistance.
• Steel coupler sleeves are hardened to resist deformation and maximize service life.
• Couplers have polyurethane valve stem O-Ring, with a temperature range of -65° to +212°F
• Ancillary coupler seals are Nitrile (Nitrile Rubber), with a temperature range of -40°F to +250°F
• PTFE or TPC-ET Anti-Extrusion ring protects main coupling valve seal from dynamic impulse pressure damage.

Features

• High flow performance, compact profile
• Easily rebuildable!
• DORS (dual opposing retention spheres) retention system prevents valve stem ejection during surge flow and pressure spike conditions.
