Technical Specifications for Piston valve

Piston valve

Shree Ganesh Engineering Works, under the brand name MESCO, is a leading manufacturer and exporter of Piston Valves designed for steam, gas, and process fluid control applications.

Our valves are engineered to deliver leak-proof performance, long service life, and easy maintenance, making them a preferred choice for critical industrial operations.

A Piston Valve is a high performance industrial valve used for reliable flow control and tight shut-off in steam, water, gas, oil and other process fluid applications. It employs a piston mechanism and sealing rings for leak proof operation, low maintenance and long service life. Piston valves are constructed of high quality materials such as cast iron, cast steel, stainless steel, forged steel, etc. Piston valves are highly durable, give good sealing and work efficiently at high pressure and temperature.
