SEVICON pneumatic switch butterfly valve has the following features:
The unique triple eccentric design can effectively prevent the valve from violent vibration during opening or closing, which improves the service life and sealing performance of the valve.
Metal hard seal structure can ensure the sealing performance in high temperature, high pressure, corrosion resistance and other harsh working conditions, applicable to a variety of fluid media.
Rubber soft seal structure can ensure the sealing performance of the valve in low temperature, low pressure, ordinary fluid media, and has better wearing-resistance and anti-aging properties.
The pneumatic actuator adopts high introduction type pneumatic piston structure, which is characterized by large thrust, sensitive action, easy control, etc., and can ensure the accurate switching and adjustment of the valve under various working conditions.
External stoke limit switch, solenoid valve, triplex and 0.4-0.7MPa gas source can achieve the switching operation and send out two pairs of passive contact signals to indicate the valve switching, which is convenient for users to carry out automatic control.
The overall structure is simple and compact, easy to install and maintain, suitable for cutting off and regulating in various piping systems.
SEVICON pneumatic switch butterfly valves are available in a wide range of materials, including WCB, 304, 316, 316L, ductile iron, PVC, CPVC, etc., which can satisfy different working conditions and user requirements.
