Pneumatic valve system has the function of each part and USES have you ever know?

Pneumatic valve system functions and purposes (1) pneumatic actuators: the parts are divided into double acting and single acting. Double acting pneumatic actuator: to control the valve opening and closing of two type. Single acting pneumatic actuator ( Spring return type) : in the gas cut off or malfunction, the valve automatically turned on or off. (2) valve: the valve is a fluid conveying system in the control unit. (3) electromagnetic valve: is divided into single electric solenoid valve and double electric solenoid valve. Single electrical solenoid valve: valve opened or closed when power supply, power valve shut or open. Double electric solenoid valve: a coil electric valve open, another coil electric valve shut. Teleportation (4) limit switch: switch valve position signal. There are mechanical, proximity, induction. (5) gas electricity locator, according to the current signal ( Standard - mA) The size of the control medium flow control valve. 6 air handling sanlian pieces: including air pressure reducing valve, filter, oil mist device, the gas source voltage lubrication, cleaning, moving parts. All landowners manual operating mechanism: manual operation in automatic control under normal circumstances. Today muffler: installed in the vent of electromagnetic valve, reduce the noise. Pet-name ruby fast connection-peg: in electromagnetic valve or actuator are connected at one end, and can use the trachea directly inserted the other end. Attending air compressor: is the pressure of compressed air generator. Zhejiang double in automatic control valve co. , LTD. Is located in the famous 'township of the Chinese pump valve' wenzhou OuBei Town, convenient transportation, transportation fast. Is a modern enterprise, the introduction of production equipment processing center, numerical control machine, at the end of the valve pressure testing of a complete set of equipment. Brought together a group of high-quality technology development and management personnel. The CAD software products and software control valve, in accordance with the ISO quality management system from the operation. Company production of pneumatic, hydraulic, electric actuators and all kinds of pneumatic complete sets of control valves. Now has two bases in zhejiang and Shanghai, the cylinder body is made of high quality aluminum alloy extrusion forming, hard oxidation treatment, the surface of the components are the use of special wear-resistant materials and high quality fittings. Greatly improve the overall performance of various kinds of actuators. Valve body made of cast iron, carbon steel, stainless steel, chrome steel, alloy steel, special steel, such as according to the requirements of the user's medium use condition, the internal valve materials and seal structure with excellent configuration meet the different requirements of customers, make the automatic control valve in a variety of pressure, temperature, and medium harsh under complicated lead cattle to ensure its tightness, abrasion resistance. Corrosion resistance and security, is to realize the remote centralized pipe, also can be individually controlled automatic device.
