Pneumatic Knife Gate Valve

MVS offers high-performance Pneumatic Knife Gate Valves designed for applications that demand automated control with reliable shut-off in fluid and semi-solid handling systems. These valves are available in wafer, lugged, and flanged end connections, suitable for size ranges from 50 mm to 600 mm, with larger sizes available upon request. Built for Class 150 pressure ratings, these valves are engineered to perform in industries like wastewater treatment, pulp and paper, mining, and chemical processing where automation, durability, and sealing integrity are critical.

Our Pneumatic Knife Gate Valve is manufactured with optional metal or resilient seat arrangements and is offered in both unidirectional and bidirectional configurations depending on system requirements. The valve’s operation is powered primarily by a pneumatic cylinder in double-acting mode, with optional electric or hydraulic actuation based on the desired control method. Designed to operate efficiently in temperature conditions ranging from −29°C to 425°C, the valve delivers consistent performance across a broad spectrum of processing environments.

At MVS, we manufacture a complete range of Cast ductile iron unidirectional pneumatic knife gate valve semi lug type and Cast ductile iron unidirectional pneumatic knife gate valve full lug type, ideal for general flow isolation tasks in corrosive and semi-solid media. For industries requiring greater corrosion resistance and longer service life, we offer Carbon steel unidirectional pneumatic knife gate valve semi lug type and Carbon steel unidirectional pneumatic knife gate valve full lug type, alongside Stainless steel unidirectional pneumatic knife gate valve semi lug type and stainless steel unidirectional pneumatic knife gate valve full lug type configurations.

To meet more demanding process conditions, our material range includes ss 304 cf8 unidirectional pneumatic knife gate valve semi lug type, ss 316 cf8m unidirectional pneumatic knife gate valve full lug type, as well as duplex steel unidirectional pneumatic knife gate valve semi lug type and super duplex steel unidirectional pneumatic knife gate valve full lug type, making sure mechanical integrity under high pressure, aggressive chemicals, and extreme temperature applications.

Engineered as per international quality standards, MVS Pneumatic Knife Gate Valves offer smooth automation, minimal maintenance, and excellent sealing performance. With their rugged construction, reliable actuation, and extensive material availability, they are a preferred solution for clients looking for precision control and operational efficiency in challenging industrial setups.
