Sophisticated processing equipment, sound detection equipment, a sound quality assurance system to ensure product quality and reliability. Pilot slow closing check valve Product Description DX7K41H pilot slow closing check valve is critical for the turbine inlet control devices, has a good seal, regulation performance, the valve is a valve factory in Shanghai Rong titanium developed in recent years, new products for a variety of domestic and foreign products through careful study and research, to create a unique structure with three eccentric as the basic type of hydraulic control valve, the field applications, the operating system is running well, this butterfly in addition to three eccentric structure also has the following advantages obvious advantages and characteristics. Main features 1, the valve drive system for the same voltage levels driving means small and large range of valve opening and closing speed regulation, early open segment of high pressure low flow control, so that the state of the butterfly valve opening moments gentle, non-violent fluctuations completely eliminate water hammer hidden within the system, and then cut into a faster rotation angular velocity, the ideal thrust and speed of the hydraulic cylinder will be set to open the disc smoothly. 2, the installation position of the valve is usually deviate reasonable placement of the disc can take advantage of a smooth closed pipeline hydrodynamic torque drive for transverse horizontal disc, the disc, the installation location of the valve will be reflected in the hydrodynamic torque Common effects of weight torque, with the closure of the gradual completion of the corner, will tend to reduce the hydrodynamic torque, torque hammer will make close instantly becomes slow and steady, which strictly eliminate water hammer phenomenon, zero Leak sealing effect will be reliably achieve reasonably tight control in this system. 3, the electro-hydraulic control system of the valve with remote control, lock the disc on and off at any speed and in any location can be accessed through the rational design of various types of hydraulic control valve is easily achieved. 4, the valve is equipped with a manual pump, when the system is powered off for some reason and can normally closed or open valve.
