Pneumatic Actuator Valve

A: Double Acting requires air pressure for both opening and closing. It’s cost-effective and ideal for general use. Spring Return (Single Acting) uses air to open and springs to close (or vice versa), providing a fail-safe function that automatically resets the valve during power or air supply failure.

A: Our standard actuators are designed for 3 to 8 bar (40 to 120 psi). For optimal performance and to ensure the 20-30% safety torque margin, we recommend a stable supply of 5-6 bar.

A: Yes. Unlike electric actuators that may overheat, pneumatic actuators are built for high-cycle applications. With high-quality seals (FKM/NBR), our valves can support rapid on/off operations in automated production lines without thermal degradation.

A: Absolutely. Pneumatic actuators are inherently explosion-proof because they don't use electricity. When equipped with explosion-proof solenoid valves and limit switch boxes (ATEX/IECEx certified), they are the safest choice for oil, gas, and chemical processing.

A: Standard speeds range from 1 to 3 seconds depending on the valve size. You can easily adjust the speed by installing speed controllers (muffler throttles) on the solenoid valve exhaust ports to prevent water hammer effects.

A: We offer a range of body materials: Stainless Steel 316 for corrosive chemicals, WCB/Cast Steel for high-pressure industrial use, and Sanitary Grade for food and beverage. Our engineers provide a compatibility check based on your medium’s pH, temperature, and concentration.

A: Our standard operating range is -20°C to +80°C. For extreme conditions, we offer Low-Temperature Seals (down to -40°C) or High-Temperature Viton Seals (up to +150°C) to ensure zero leakage.

A: Our pneumatic actuators are designed for over 1 million cycles. Under normal clean air conditions, they are virtually maintenance-free. We recommend checking the air filter and lubrication (if required) every 6-12 months.

A: Yes. To support your engineering team, we provide STEP, DWG, and PDF files. This allows you to verify clearances and mounting dimensions in your 3D system model before purchasing.
