Features & Benefits
Smooth Bore Low Pressure Drop
Cylindrical piston provides straight-through flow when open with minimal restriction, protecting sensitive gauges from pressure spikes.
Rising Stem Position Indicator
Stem rises visibly when valve opens, providing clear remote indication of valve position without position switches.
Positive Metal-to-Metal Shutoff
Matched-lapped piston and integral seat provide reliable shutoff even after years of service in dirty or viscous media.
Union Bonnet for In-Line Service
Union bonnet allows packing and plug replacement without removing valve from piping, reducing maintenance downtime.
Gauge Snubber Option
Optional internal snubber orifice dampens pressure pulsations, extending gauge element life in reciprocating pump and compressor service.
