Product Description
Pneumatic diaphragm valve
Dual role of the valve cylinder, the use of superior or inferior into the air intake valve to remote control the valve, easy to operate. The medium in the cylinder: Compressed air, nitrogen. Simple structure, easy manufacturing and maintenance; Work trips in small, short headstock; The closure body (valve) and the use conical valve seat sealing surface sealing, the closure of our small, erosion-resistant, reliable sealing. For the replacement of seat-type valve seat, can be any combination of on and off pieces of the matching sealing surface materials to meet the conditions, good using method can extend the service life.
Specification standard
Remarks:
Pneumatic diaphragm valve
1. P stands for valves positioner; R— Pressure servomotor.
2. The allowable pressure deviation is P2=0: The valve is on turning off situation, P reaches the highest level.
3. If the maximum pressure is more than 1.0Mpa, we advice to weld hard or other suitable materials as the tapon and seat surface.

Zhejiang Zhongte Pneumatic Valve Fitting Co., Ltd. Specializes in manufacturing pneumatic/electric actuators and control valves. Our company is located in Shacheng Industry Park called "Chinese valve city".
Our company was built in 1994 and covers an area of 5, 200 square meters. We have set up head office, sales department, technical department, purchase department, production department, QC department, supply department, and finance office in our company. We keep trying for ten years, and now Zhongte has grown to be a company with two subsidiary companies.
We have perfect process centre and quality inspection equipment. The process centre owns lathes, milling machines, and boring lathe numerical control machines for 40qtys. There are 5 imported vehicle process centers and many high quality numerical machines. At present, we mainly manufacture pneumatic actuators, pneumatic ball/butterfly valves, electric actuators, pneumatic/electric control valves, and other wise products. Our products are widely used in petroleum, chemical industry, electric power, metallurgy paper making, light industry, and pharmacy and food industry.
Our company absorbs advanced technologies. We use CAD, CAE, CAM, FEA and finite element analysis to design. Our products have attained ISO9001: 2000 international quality system certification.
We hope that we may return a good reputation by high quality products, reasonable prices and perfect service for customers' support with the aim of a long-term cooperation based on equality and mutual benefits.
