High performance wafer-type pneumatic stainless steel butterfly valve

D672F Pneumatic High Performance Double Eccentric Double Clamp Butterfly Valve

D672F adopts a clamp connection, double eccentric butterfly valve structure, and pneumatic actuator. The current page diameter is DN25-DN800, and the pressure configuration includes PN16, Class150, and JIS10K. The material fields include WCB, 304, and 316L.

What is the function of a double eccentric structure?

The double eccentric structure allows the butterfly plate to quickly detach from the valve seat after opening, which helps to reduce the continuous friction and opening and closing torque of the sealing pair. The actual sealing material, allowable pressure difference, and bidirectional sealing ability should still be confirmed based on the specific product structure.

What is the difference between switch type and adjustable type?

The switch type mainly executes fully open and fully closed commands; Adjustable configurable locator that changes the butterfly plate opening based on control signals. Whether it is suitable for fine flow regulation also depends on the characteristics of the butterfly plate, pressure difference, and the selection of the actuator, and cannot be judged solely by installing the 4–20mA locator.

How to configure pneumatic accessories?

Electromagnetic valves, filtering and pressure reducing devices, limit feedback and locators can be configured according to the project, and single or double acting, gas source pressure and safe position for gas loss can be confirmed. Profinet、HART、 Explosion proof certification and IP rating are based on the actual accessory model.

Frequently Asked Questions

Does double eccentricity necessarily mean a metal hard seal?

Not necessarily, eccentric structure and sealing material are two different selection dimensions.

Does D672F support 4–20mA by default?

Not default, the adjustable configuration locator can only work according to the corresponding control signal.

Can high-performance butterfly valves achieve the fixed Class VI leakage level?

It cannot be determined by name, and the leakage requirements should be based on the actual sealing structure and test documents.
