Pneumatic stainless steel lined PTFE proportional adjustment butterfly valve is driven by pneumatic single acting or double acting actuators, with stainless steel 304/316L as the valve body. The inner lining material is composed of corrosion-resistant [FA, FEP, PTFE], and can be equipped with a filter regulator to purify and reduce the pressure of the driven air. The valve locator receives 4-20mA analog quantity for proportional adjustment, and PLC/DCS receives feedback on the position of the valve. The two sides are connected by flange plates.
