Product Details

                                          API Wedge Type Gate Valve



Brief introduction of  API wedge item gate valve

The opening and closing part of the flange stainless steel gate valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used wedge gate valve form a wedge. The wedge angle varies with valve parameters, usually 50, and 2°52' when the medium temperature is not high. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce slight deformation to improve its manufacturability and compensate for the deviation of the angle of the sealing surface during the processing. It is called an elastic gate.

Product features: ①The product design meets the requirements of foreign advanced standards, with reliable sealing and excellent performance. ②Compact and reasonable structure design, beautiful appearance. ③Using wedge-type elastic gate structure, rolling bearings with medium and large diameters, easy to open and close. ④Valve body materials are complete in variety, and packing and gaskets are reasonably selected according to actual working conditions or user requirements, which can be applied to various pressure, temperature and medium working conditions. ⑤Adopt a variety of domestic and foreign pipe flange standards and flange sealing surface types to meet various engineering needs and user requirements.
