as a large professional valve manufacturer, valve is the valve actuator accessories and fittings related information is as follows:

Industrial Valves fittings and accessories:

with the improving of the industrial requirements, and the valve product performance requirements are also rising. Some businesses will vigorously improvements in the structure of the valve, also has a lot of manufacturers will be added to the valve accessories and spare parts to improve the performance of the valve and purpose, make the valve to use more simple, and other functions.

a lot of Industrial Valves fittings and accessories, mainly around the intelligent remote control and multi-function development, is common in the improvements on the drive way, also have to add in internal structure.

valve accessories mainly include:

1, the pneumatic actuators, pneumatic actuators is mainly divided into that of single and double action is single acting spring return type structure, the principle of double action is gas-off, external regulation generally choose double-acting pneumatic actuators.

2, line of electric actuators are: common electric actuators are straight stroke, stroke, small, explosion-proof, electric actuator structure is relatively complex, the construction cost is higher, its performance is stable, open/close quickly, suitable for long distance control system.

3, hydraulic actuator, hydraulic actuator is by the hydraulic pressure can be converted into mechanical energy of a device that basically has two kinds of linear and rotary. Its structure is relatively complex, high cost is the special working conditions and requirements of high use of product, market general rate is smaller.

4, gas-liquid linkage actuator: linkage actuator pipeline gas or gas and liquid nitrogen as the power, the hydraulic oil as a transmission medium drive pipe opening and closing of the valve. Mainly used in natural gas, liquefied gas, nitrogen, gas tank as multifunctional drive device, gas, etc.

5, electro-hydraulic linkage actuators: electric hydraulic linkage actuator consists of two parts, control module and power module, the function of the intelligent control modules for controllable motor accept command, control the power module, line by line or angular displacement output from vigorously, pneumatic control object, through its displacement feedback at the same time, complete the adjustment process, control to realize various functions.

6, manual actuators: manual actuators is to improve the current instability and manual control air pressure is insufficient, occurs when the air pressure and current special circumstances can't control current and pressure or installation and maintenance, the open hand feedback device, can be manually controlled rapidly.

actuator accessories:

locator, electro-hydraulic servo device, servo amplifier, electrical switches, air filter, relief valve, valve position transmitter, valves, solenoid valves, limit switches, intelligent module, alarm, quick exhaust valve, the signal generator.

as domestic high-end valve manufacturer, has been in response to national policy and called for, committed to research and development, manufacture, electric butterfly valve, stainless steel ball valve, discharge valve, electric gate valves, stainless steel gate, stainless steel valve, stainless steel check valve, high pressure gate valves high-quality let customer trust of good valves, valve to keep the traditional valve product sales profits to escort for the innovation research.

need huge investment, so it is important to shop with caution.
