Hand Shut Off valves are compatible with all CFC, HCFC and HFC Refrigerants and oils and other Industrial gases / fluids non-corrosive to Steel and Brass.

• Valve Body: Hot Forged Brass (BS-218).
• Spindle: Extruded Brass.
• Diaphragm: Stainless Steel.
• Knob: Thermally stable engineered plastic.
• Spring: Specially treated Steel.
• Seat: Stainless Steel / Nylon.

• Superior Valve Body design allows gripping while tightening / loosening the Flare Connections.
• Superior Bonnet Design allows easy access when disassembling / assembling for solder connections.
• Full port openings for maximum flow, minimal pressure drop and long life.
• Back seating minimizes moistures intrusion.
• Stainless steel Diaphragm for positive isolation ensures hermetic sealing of the flow area.
• Thermally stable plastic Knob for easy operation in wide temperature range.

• Maximum working pressure with flow in direction of arrow mark 400 psig.
• Working Temperature Range: (-30°C + 100°C).
• Individual Pneumatic Testing in Open/Close position at 400 psig.

• While brazing solder connection, disassemble the Valve and use suitable filler material for brazing.
• While re-assembling the Valve allow the Valve body to cool to room temperature and clean the part thoroughly. For leak tight sealing use Torque wrench set at 30 Lb.Ft to avoid damage to the Diaphragm and Valve.
• If Valve locks in open Position grip Hand wheel with soft cloth and turn with reasonable force in Clockwise direction (towards arrow directing CLOSE position)
