Pneumatic Valve
Engineered for air-operated valve control and efficient automation in industrial processes.
MD Valves manufactures high-speed Pneumatic Actuated Valves engineered for rapid, reliable isolation and process regulation across demanding industrial piping systems. Powered by rack-and-pinion and heavy-duty scotch yoke pneumatic actuators, our valves provide dependable fail-safe automated switching with cycle speeds measured in milliseconds.
- Actuator Configurations: Available in both Double Acting (DA) and Spring Return / Single Acting (SR) fail-safe setups.
- Control Accessories: Integrated Namur solenoid valves, electro-pneumatic positioners (4–20 mA), and weatherproof micro-switch limit boxes.
- Rugged Metallurgy: Premium Stainless Steel (SS 304, SS 316, SS 316L) bodies built to resist aggressive chemicals and high pipeline pressures.
