Product Description

This wafer butterfly valve has a cast iron body, 316 S.S disc, EPDM/PTFE etc seat and a spring return or double acting pneumatic actuator making it suited to a wide range of industrial applications. These wafer butterfly valves will fit all standard flanges and are operated by a high quality spring return (rack and pionion design) anodised aluminium pneumatic actuator. This enables a fail safe position if air should be lost. The unique bonded catridge design of the butterfly valve gives it a longer life span, allows vacuum to be run through it and enables the seat to be replaceable if ever the need should arise. Common applications include water trucks, irrigation, water treatment and other industrial applications. 

Features:

Ball Material: Carbon steel/stainless steel

Actuator Housing Material: Aluminum

Actuator Type: Spring return and double acting

Upgrade: Solenoid valve, air filter, limit switch

316 stainless steel body and a PTFE seal stand up to aggressive and corrosive solutions in chemical-processing applications. Their ball-valve design allows these valves to handle at least three times the flow of standard flanged valves. For faster actuation than motor-driven valves, they operate on compressed air. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). These valves automatically start and stop flow and don't require a minimum pressure drop between the inlet and outlet for operation.

Valves are full port, so they do not restrict flow. The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.

Single-acting(spring return) actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied to close them, so they do not have a valve starting position.
