What is unique about pneumatic valve?

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. With the enlargement of the pneumatic valve use range, use the crowd also has a lot of different culture level. So there are a lot of people for pneumatic valve of air valve and air valve kay some confuse. Let's take a look at the differences between them. Pneumatic valve ( Also known as the two valve or switch valve) Open valve and air valve can be divided into gas. As the name suggests, the gas valve open refers to using pressurized in the instrument air to the actuator, the valve opens. When actuators will be its instrument air when removing the valve closed. Gas valve. Pneumatic valve are both open means, because the process system air source fault broken happens sometimes, according to the needs of technological process at this time, some valve to open, Such as cut-off valve) , from valve to close ( Such as exhaust valve) So that the designer in the process design according to the need and use gas valve open or close the valve.
