Body: Ductile iron GGG40/GGG50 Disc: Ductile iron+EPDM/NBR Stem: Stainless steel Size: DN40-DN600 The opening and closing part of the wedge gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The wedge gate valve can only be fully opened and fully closed, and is not suitable for

Different from parallel gate valves, wedge gate valves also have wedge single gate valves. The two sealing surfaces of the most commonly used wedge gate valve form a wedge, and the wedge angle varies with the valve parameters, usually 50. The gate of wedge gate valve can be made into a whole, which is called

The Filter Y type-Screen is an attractive and economic solution for Landscape application as well as Municipal application. It varies from a small size of ¾” to large size of 2-1/2″. By utilizing the Y shape, will fit most of the installation infield. The Y filter is the perfect solution for fertilizer usage where soluble

1. Raised surface pressing surface: Features: simple structure, easy processing, easy loading and unloading, easy anti-corrosion lining; Use: the pressing surface can be smooth and suitable for occasions with PN less than or equal to 2.5MPa; With grooves (2 ~ 4, width x depth of 0.8mmx0.4mm, cross section of triangular circumferential groove), the gasket is

1. When the flexible rubber joint is installed in the pipeline, it must be in a natural state, and the product shall not be deformed artificially. When the pipeline medium is acid-base resistant, oil resistant, high temperature resistant and other special materials, the joint one gear higher than the working pressure of the pipeline shall

1. It is forbidden to install the rubber flexible joint beyond the displacement limit. 2. When installing rubber joints on flat ground, in the air and vertically, the actual working axial displacement pressure of the rubber joints shall be less than the supporting force of the pipeline, otherwise anti pull off devices shall be installed

Rubber joints are also called rubber pipe soft joints, flexible rubber joints, rubber soft joints, flexible rubber joints, high-pressure rubber joints, rubber shock absorbers, compensators, etc. According to the connection mode, it is divided into loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into 5 kinds:

Butt welding flange is that the diameter and wall thickness of the interface end are the same as that of the pipe to be welded, and then welded as two pipes. The flat welding flange is a concave platform with the inner hole slightly larger than the outer diameter of the pipe, and the pipe is

The solid solution process of stainless steel flange has a great influence on the corrosion resistance and appearance brightness of stainless steel, and plays a decisive role in the processing performance of stainless steel. Therefore, the heat treatment process of stainless steel is very important in the production of stainless steel flange.   1、 Solution temperature. According

Anchor flange is a kind of engineering component. In places with low pressure, short pipes with thrust rings can be used instead, or called through wall sleeves. For the connection of fixed pipes that are required to be buried underground or not maintained for life, and when the pressure is required to be high, conventional
