Product Description
With a Buildin Strainer Piston Auctuated Slow Shut Check Valve
MODEL NO.: GL98004
Δ The KARFAR model GL98004 is mainly mounted at outlet pipeline of the pump station of water supply, transport, pressure loading, diving and sewage system. It has multiple purposes as check valve, globe valve, control valve, filter and pressure surge eliminator.
Δ This valve can be used as check valve with adjustable opening and closing speed. Users can adjust the speed according to your specific site situation so as to prevent pressure surge and slamming noise.
Δ Cost & Space saving: This multifunctional series valves are with a built-in filter so it is much more cost saving and space saving than one normal multifunctional hydraulic control valve and one filter device.
Main materials:
1) Body and bonnet: Cast iron, ductile cast iron, WCB, WCA, WCC,
A351, 304, 340L, 316, 316L, 17-4pH etc.
2) Piston jar: Stainless steel - A351, 304, 340L, 316, 316L, 17-4pH etc.
3) Piston seat: Cast iron, ductile cast iron, WCB, WCA, WCC, A351etc.
4) Seat and disc: WCB, WCA, WCC, A351, A744etc.
5) Stem: Stainless steel etc.
Model GL series Piston actuated type can be modified to Diaphragm actuated type.
