Valves & Actuation

The Type 567 is a wafer style butterfly valve rated for pressures up to 150 psi and temperatures of up to 140° F for PVC and 176° F for CPVC, also available in polypropylene and PVDF. Better chemical compatibility is achieved because the inner body is the same material as the piping. The Type 567/578 Butterfly valves have a unique eccentric design that means the disc is not in contact with the seal in the open position. The result is less wear and operating torques half that of previous models. Georg Fischer double eccentric butterfly valves require approximately 50% less operating torque than boot-style competitive valves. Lever and gear operators are both available. In the lever version, the opening angle is clearly indicated on the index plate.

The Type 582 Pressure Reducing Valve shall control downstream pressure. The set pressure is controlled via an adjustment screw. The spindle is of non-rising design. The bonnet connection is of threaded design. The seal material is indicated by color coded external tab. Following assembly, every valve is tested and certified bubble tight exceeding Class VI standards. The Compact design enables installation even where space is limited. Threaded bonnet eliminates the need for body assembly bolts. Significantly shorter lay length with union ends. No need to re-torque due to threaded bonnet. Easily adjusted set pressure with non-rising spindle. Constant and low vibrating control behavior. Tightness resistant to temperature cycling. Adjustment of set pressure possible during operation. Pressure gauge options for aggressive media. Connection options in true union, spigot or flanged. Low pressure spring set available (4-44 psi) Optional Pressure Gauges. Pressure gauge mounting on either side of the 582 valve to accommodate required installation direction. Standard gauges are 304 stainless steel or brass with either EPDM or FPM elastomeric seals. Valve bodies of all varieties can accommodate two pressure gauges.
