Description
Pneumatic butterfly valve
The Pneumatic Butterfly Valve functions as a dependable versatile valve which operates in multiple applications including potable water and wastewater systems as well as seawater and HVAC and sanitary and chemical systems. The valve body exists in different materials including cast iron and ductile iron and aluminum and stainless steel and CF8 and CF8M and CF3M and double stainless steel (2507/1.4529). The valve disc consists of stainless steel material (CF3M/CF3/CF8M) and features a single-piece design that minimizes leakage risks and pressure loss.
The valve operates at output torques ranging from 10Nm to 8000Nm while supporting control functions through Double acting and Single acting normally closed and Single acting normally open configurations. The valve provides excellent flange compatibility through EN 1092 PN 6/PN10/PN16 ASME Class 150 and AS 4087 PN 10/ PN 16 and JIS 5K/10K and ISO5211 Top flange options. The valve operates within a temperature range of -40 °C to + 200 °C based on material selection and pressure conditions. The valve includes pneumatic accessories including solenoid valves and limit switch boxes and filters and E/P positioners and hand wheels for user convenience.

FAQs
What is butterfly valve used for?
Butterfly valves serve as essential control valves which find applications across various industrial and commercial sectors. The primary function of butterfly valves involves flow control through their ability to completely stop or partially regulate fluid flow rates. The valve design includes a circular disc which spins on an axis inside the valve body to enable full closure or partial opening for flow regulation.
What is a wafer-type butterfly valve?
The wafer-type butterfly valve functions as a flow control device which serves multiple industrial applications. The valve consists of two semicircular plates which hinge at the center to create a disc that functions like butterfly wings for opening and closing operations. The stem connects to a handle or wheel which enables users to operate the valve by turning it to move the disc up or down.
What is a pneumatic butterfly valve？
The pneumatic butterfly valve operates as a control device which manages liquid and gas movement through pipeline systems. The valves operate on large diameter pipelines by using circular disc rotation to control material flow.
The pneumatic butterfly valve provides multiple benefits over other valve types because it remains lightweight while being affordable and simple to maintain and adjust and highly reliable and suitable for different fluid media types. The devices support additional process control through the installation of positioners and limit switches as accessories.
