DESCRIPTION

This valve is designed in such form that when the difference between the upstream pressure and the downstream pressure overcomes the force exerted by the spring, the plug opens, allowing flow through the outlet connection. The flow through the valve increases proportionally to the increase of that pressure difference. To increase the cracking pressure of the valve, the spring must be compressed by turning the adjustment cap clockwise.

FEATURES

• Angle pattern.
• External adjustment without disassembly the valve.
• Zero leak until the set point.
• External range engraving.
• Lock wire feature secures a given pressure setting.
• Low internal friction, reducing hysteresis.
• Reliable retention of the sealing o'ring.
• High flow capacity.
• Male and female connections.
• 100% tested and calibrated in factory.
