Butterfly Valve

Through over 50 years of R&D and manufacturing, Our products include globe type (HKG,HKP,HKZ,HKE) and angle type(HKGA, HKPA,HKD,HKT,HKEA,HKA), with high control precision, stable performance and reliable quality, which are specially explored for all kinds of severe working service conditions. This series supplies the different pressure reduction type according to the pressure drops and fluids under the multi-stage pressure reduction principle; The higher pressure drop will be decomposed into several smaller pressure drops so as to reduce erosion and vibration from fast flowing. This series can prevent flashing and cavitation, and reduce the noise and has large range application of temperature. This series of products is widely used in petroleum, chemical industry, light industry, pharmacy, paper-making, metallurgy, power station etc.

• Product Features

​

High control precision. The internal part design is simulated via CFD, and reaches the technological requirements through the professional software analysis and computing, and experimental verification. The flow characteristics conform to the international standard IEC534.

Complete product specifications. The products cover a wide range (high, middle and low-end series), along with series products designed adapting to special working conditions. With strong universality, the requirements of different working conditions and control performances can be satisfied by directly replacing the part types inside the valves.

Autonomous core control technology. The company possesses multiple high pressure difference control technologies to cater to special requirements under different working conditions. Moreover, it masters the hardening process technologies of key parts and components, which can improve the product performance and enhance their reliability. Meanwhile, the compact and reliable internal and external leakproof structural design meets the international standard requirements like TA-Luft/Shell SEP77/312.
