What are the pneumatic butterfly valve accessories

Pneumatic butterfly valves generally consist of a valve body, a pneumatic actuator and accessories. Switching and adjustable pneumatic valves are realized by matching different accessories. Positioner, solenoid valve, limit switch and filter pressure reducing valve.

Limit switches

The limit switch is an industrial device that feedbacks the opening and closing of the valve body. At the same time, it can feedback signals to the system, so that you can know the status of the valve by checking the system.
● Clear viewing window for easy observation of valve opening and closing
● IP67 protection grade can be used normally outdoors
● Explosion-proof type is available for the applications required.

Solenoid valves

The full name is a solenoid replacement valve. The function is to switch the air source to power the air source to open and close the valve. Double actuator with a 2 position 5 pass solenoid valve and a single actuator with a 2 position 3 way solenoid valve. The solenoid valve scores electronically controlled and double electronically controlled, the single electronically controlled is electrically opened, the power supply is disconnected and if the valve needs to remain open, the power supply continues, easy to heat and reduces service life. The dual electric control has two head coils, one of which is electrically open, power is kept in place and other electrical power is required and only energised from the switch and the remaining time can extend the service life.

Filtering through pressure reducing valves

The filter as well as the pressure reducing valve is to filter the system air moisture for impurities, and decompression with, this accessory data can quickly grow the problem cylinder and solenoid valve use network life. The models are also particularly numerous, there is a separate filter, a separate pressure reducing valve, also a filter control decompression, also different filter decompression oil misters in one, i.e. single parts, two parts, three parts.

Positioner

A positioner is an industrial device that receives or feeds back signals and delivers air to a pneumatic actuator to adjust valve opening and closing.
● Responsive and precise adjustment
● Available in single-acting types and double-acting types
● Explosion-proof type is available for the dangerous applications
● Helping you control the valve remotely
