Introduction
GB 12232-89 General valve flange connection cast iron gate valve is a kind of valve commonly used in the chemical industry. By running the the valve gate up and down, the valve can be opened and closed. The GB 12232-89 General valve flange connection cast iron gate valve, due to its high precision manufacturing process and excellent corrosion resistance, has become the valve of choice for many chemical and petrochemical plants.
Overall Description
The GB 12232-89 General valve flange connection cast iron gate valve consists of main parts including the main body, stem, gate, bonnet, seat, seals, etc. It is a kind of regulation valve which is applicable to pipeline and equipment controlling pressure, temperature, flow and so on. When the valve is closed, the stem and gate move up, so the fluid flow is blocked. The gate is connected to the stem through the bonnet, and the stem is operated by throttling the gate up and down in order to control the flow. The gate is held in position by the valves stem, and the stem is sealed with the valves bonnet.
Features
The GB 12232-89 General valve flange connection cast iron gate valve has the following advantages:
1. The body and the bonnet are connected by precision machining and sealed with a bellows seal, providing high reliability and long service life.
2. The gate seat is made of wear-resistant F-04 stainless steel, and the gate is designed with a replaceable simple structure.
3. The whole body is of cast iron, which has strong corrosion resistance.
4. The stem is coated with Stellite for wear resistance and corrosion resistance.
5. The gate is equipped with an oil injection system, which can make the valve operate better.
6. The valve is designed for bidirectional seals, which can effectively prevent leakage and make operation smoother.
