As being leading provider of high quality pneumatic system, we offer best quality pneumatic diaphragm control valves. To offer best quality valve, we fabricate our series of valve by global production standard. Our qualitative product range has earned us a status of major manufacturer and exporter of Pneumatic diaphragm control valve.
It is suitable to vast range of industrial activities. Polyurethane diaphragm and high grade gland packing material made the device robust. It is easy to install and easy to operate. It is used for high temperature, high pressure applications.
It is available with the pressure range between 150# to 900#. It can be used for water, oil, gas and other chemicals and fluids. It is prefer for its best features like reliability and best performance. It is also prefer most for its better durability and least maintenance.
It is a modulating control valve that uses a flexible diaphragm actuator to convert air pressure into linear stem movement, precisely regulating the flow rate, pressure, or temperature of a fluid.
They provide highly precise flow regulation, high sensitivity to control signals, reliable shut-off, and low maintenance due to few moving parts in contact with the process fluid.
Yes, by choosing appropriate body materials (like stainless steel CF8M) and corrosion-resistant linings or diaphragm materials (such as PTFE or EPDM), they handle acids and corrosive chemicals exceptionally well.
A direct-acting actuator pushes the stem down with increasing air pressure (air-to-close), whereas a reverse-acting actuator pulls the stem up (air-to-open), providing custom fail-safe modes.
They can be fitted with electro-pneumatic positioners, limit switches, solenoid valves, air filter regulators, and manual overrides for enhanced control and safety.
Selection is based on the flow coefficient (Cv), fluid properties (density, viscosity), inlet/outlet pressure, temperature range, and desired flow characteristics (equal percentage, linear, or quick opening).
