Valves & Actuation

Filterchem Pressure Regulators sense downstream pressure in fluid lines and open or close to maintain a selected downstream pressure. These valves are used to protect equipment and filters from excessive line pressures. These valves are adjustable from a range of 5 to 70 psi (5 to 75 psi for 1/2" size). Filterchem Pressure Relief Valves protect equipment from excess pressures by opening up at a selected pressure and relieving liquid line pressure back to a holding tank or drain. These valves are adjustable from 10 to 80 psi. Filterchem Pressure Regulators and Relief Valves are of molded construction of Type 1 PVC, with Viton® o-rings and PVDF-coated springs. Regulators are also available in polypropylene, and the pressure relief valve is also available in PVDF Kynar®.

Georg Fischer Type 304 Y-Check Valve is a weighted angle check valve and is used to automatically stop flow in the reverse direction when the fluid in the line stops. The valve closes by the dead weight of the weighted seat and functions when mounted in either the horizontal or vertical plane.  Type 304 Y-Check Valves are superior to spring-loaded checks for corrosive service since they are not temperature sensitive. Y-Check valves generally have tighter shut-off characteristics than ball check valves at the same pressures. Georg Fischer Type 304 Y-Check Valves feature a transparent PVC construction which allows for inspection of the position and condition of the valve piston and seat.
