Valve fittings are also a very important part. Different valves are usually equipped with different valve fittings. For pneumatic valves, its valve fittings include solenoid valves, limit switches, and pressure reducers, filters, and oil mist. The gas source consists of a triplet.
The valve fitting solenoid valve mainly has two types of five-way and two-position three-way. The two-position five-way solenoid valve is usually used with the double-acting pneumatic actuator. The two-position three-way solenoid valve is used together with the single-acting pneumatic actuator. The pneumatic valve is used to switch the air intake and the air source through the solenoid valve. Venting to achieve the function of opening and closing the valve.
The valve accessory limit switch is a signal for opening or closing the remote transmission valve. In special occasions where flammability and explosion are required, the explosion-proof limit switch should be selected. The pressure reducer in the valve fitting is mainly for the gas source voltage regulation, which can adjust the cylinder pressure. The filter and the oil mist filter can filter the impurities in the air, clean and automatically add lubricant to the cylinder.www.dmgcastings.com
