Note: according to different valve torque, different air pressure and different actual conditions, choose the matching actuator, and its relative shape and size also change

Accessory selection
Solenoid valve	Double action selects two bit, five - way, single function, two - bit, five - way, single - control, double - control
Gas source treatment triple parts	Gas source for pressure regulation, filtration, cylinder lubrication
Limit switch	Remote feedback switching signal
Hand operating mechanism	The valve can be manually opened and closed
Positioner	Enter analog signals (4-20mA or 0-10V) to adjust valve opening
Remarks	The above accessories are not standard accessories. If they need to be configured, when ordering, the electromagnetic valve and limit switch can be divided into explosion-proof and non explosion proof. If you want explosion proof, you must also indicate the explosion-proof grade

Pneumatic ball valve is the important executive mechanism of industrial automation control system, remote centralized control can meet the needs of computer program; now widely used in petroleum, chemical industry, gas equipment, nuclear power equipment, water treatment, air conditioning, iron and steel metallurgy, industrial furnace, canned equipment, brewing equipment, drying equipment vacuum equipment, surface treatment, bio pharmaceutical, food machinery, textile, papermaking and other industries.
