- Gate valve classificationThere are many standards for gate valves, and most of the connection length are also different. They are mainly divided into the following categories: ANSI, DIN, BS, JIS, GOST, SABS etc.
- Installation of gate valveThe quality of valve installation directly affects the future use of valves, so construction units and production units should pay attention to this.
- Maintenance of gate valveThe purpose of valve maintenance is to extend valve life and ensure reliable operation.
- What is the working principle of the check valve?Check valve is an automatic opening and closing valve, it does not require manpower or other operations.
- What are the working characteristics of the check valve?The working characteristics of the check valve are large load changes and small opening and closing frequency. Once in the closed or open state, the service cycle is very long and does not require the rotation of moving parts.
- New Year's Day Holiday NoticeAccording to the country's specific arrangements for the
- The working principle of the check valveUnder the action of the fluid pressure flowing in one direction, the valve disc opens, when the fluid flows in the opposite direction, the fluid pressure and the self-coincidence of the valve disc act on the valve seat, thereby cutting off the flow. Among them, the swing check valve belongs to this
- ANSI Standard Resilient Seated Gate Valve N.R.S.The difference between rising stem gate valve and non-rising stem gate valve:1. The rising stem gate valve can see the screw rod, but the non-rising stem gate valve cannot see the screw rod.2. The rising stem gate valve raises or lowers the valve clack through the threaded transmission of the valve
- ANSI Standard Resilient Seated Gate Valve N.R.S. with Denso FlangeFeatures of Electric Flange Gate Valve:1. The valve adopts pressure self-tightening seal or valve body and bonnet gasket seal structure, which is safe and reliable to use.2. The valve disc adopts the structure of double rams with universal top in the middle, which can automatically adjust the coinci
- BS Standard Resilient Seated Gate Valve Non-rising Stem with SprocketFeatures of Chain Drive:1.Chain transmission is a widely used mechanical transmission, which relies on the meshing of sprocket teeth and chain links to transmit movement and power.2.Compared with belt transmission, chain transmission can maintain an accurate average transmission ratio, high transmis
