Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive. They control the admission of steam into the cylinders and its subsequent exhausting, enabling a locomotive to move under its own power. The valve consists of two piston heads on a common spindle moving inside a steam chest, which is essentially a mini-cylinder located either above or below the main cylinders of the locomotive. A piston valve is a device used to control the movement of fluid along a tube or pipe by using a linear motion of the piston in the chamber or cylinder.
Piston valves are manufactured for better industrial performance by minimizing maintenance and saving production costs. Klinger has been at the forefront of piston valve technology since 1922. Featuring a variety of different types of flanges, threads, sockets and standards according to DIN and ANSI, piston valves complements the various types of Klinger valve production. The Klinger piston valve is characterized by a sealing system and a ring that ensures tightness. Thus it can prevent contamination of the surrounding environment. The piston valve sealing element is formed by a stainless steel piston, which is closed by two rings. In this configuration, the upper valve ring ensures tightness to the air, while the lower ring provides a sealing in the bore. The large surface of the ring leads to optimal sealing. To facilitate movement during high pressure, the pistons in the KVN VIII series, DN 65 to 200, are manufactured with a pressure balance design. When closing the valve, the piston pushes possible contaminants in the medium away from the inside of the valve ring. As a result, even contaminated media can be sealed tightly, preventing damage to the surface. If you need a piston valve, please contact us. We have piston valve in ready stock status.

Excellent ideas are lasting In the year 1922 Richard KLINGER the founder of this company had an idea, the principle of which is still valid today. He designed the first piston valve. He replaced the sealing system of a conventional globe valve with a cylindrical piston and two elastic replaceable jointing rings.

They find application for a variety of media in process and utilities like saturated steam, superheated steam, heat transfer fluids, nitrogen and more. Our piston valves are unique in their ability to provide a perfect inline shut off and no gland leakage. This ensures zero inline/external leakage.
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.
