Chongqing Shizhuang: Independent research and development of new pneumatic piston program control valve

According to the market demand, Chongqing Shizhuang Instrument & Meter Co., Ltd. has launched a new program-controlled shut-off valve, the 5103 pneumatic piston program-controlled valve, after its independent research and development for the special media and control needs of the chemical industry.


The 5103 pneumatic piston program control valve is one of the SZCV series products. It is mainly used in conjunction with solenoid valves and proximity switches, and is used in the shut-off control system for exhaust gas treatment in petroleum and chemical industries. It has been put on the market in batches.

It adopts a double-acting cylinder piston actuator with compact structure and large output force, which can be quickly closed and safely vented. The special packing type ensures the excellent sealing and wear resistance of the product, meets the frequent working conditions, and has a service life of more than 1 million times. The unique spool seat structure provides a tight shut-off function.

Common Fused Magnesite

Fused magnesia is mainly made of magnesite with 47% content and fused in electric arc furnace. The chemical indexes of fused magnesia can be divided into six major items. 1, Magnesium Oxide content; 2. Silica content; 3, iron oxide content; 4, aluminum oxide content; 5, caustic soda; 6, body density; Fused magnesia products have high purity, large crystal particles, compact structure, strong slag resistance material, good thermal shock stability, is an excellent high temperature electrical insulation material, is also an important raw material for high-grade magnesia bricks, magnesia carbon bricks and amorphous refractory materials.
