Forbes Marshall Piston Valve PSVAL
Zero inline leakage : 480 to 600 % higher sealing area. Class VI bubble tight shut off : burnished piston sealing. Zero gland leakage : No gland packing. Soft seated Sealing : Stainless steel reinforced graphite piston rings. Perfect interface fit : Positive sealing effect and burnished piston. Interchangeability of parts : Universal sealing rings. No special adaptation for spare parts. No water hammer : The lantern bush cage guides the piston movement. Variable orifice created by the lantern bush and piston eliminates sudden shocks and water hammer. In-line maintenance : Critical components can be replaced without removal of valve from line. No wire drawing : The valve seating is on the sides which eliminates the possibility of wire drawing effect Protection of wetted parts : In open and closed condition, piston remains enclosed in sealing rings and is hence protected from erosive or corrosive material.
