Established in 1993, Guanfa Valve Manufacture Co., Ltd. is specialized China valve manufacturer and distributor of valves, hoses, tubes and pipes. Our oem valves are suitable for acid, alkali, water, steam, seawater, coal gas and natural gas. They are widely used in petroleum, chemical, paper making, fertilizer, brewing and metallurgy. The use of specialized software of Pro/E and CAD has shorted the P&D and trial manufacture cycle, and greatly improved the service life and dependability of products. Our high-quality products have been exported to the North Amercia, UK, USA, Germany, Italy, India, France, Australia, Japan.

The vlave is consist of a driver and a valve body .The driver adopts the synchronous motor in order to make its performance more stable and prevent the water leak. Valve body is plated with rustproof brass,and chromium on the surface. Low power, the motor only consumes the power when the valve door is opening or closing. It is set the limit relay contact inside to make the motor longer life. The motor and the valve body can be separated and connected in short time, in order to install it more easily. Provided with manual switch, the power will be recovered automatically when finish the adjustment.

40cr is used as inlet air valve material, featuring a stable performance, a good hardness, high temperature resistance, wear resistance and a good mechanical performance. 4criosizmo is used as exhuast valve material, featuring high temperature resistance, not shedding off, oxideresistance wear resistance, good anti-acid performance, excellent comprehensive performance and stable. Hence, a normal operation of engine is assured.
The product is softly nitrogenation as a whole, with the depth of nitrogenation being above 0.05mm, surface hardness HM(200g)590and above, small head RF hardening, with a hardness being between HRC 50 temperature-58 temperature.
