Product Description
1. Side mounted cast steel fixed ball valve is a 90 degree rotary valve. The ball is fixed by upper and lower trunnions to avoid lateral displacement of the ball under pipeline medium pressure, prevent seat damage and greatly improve sealing performance.
2. The seat adopts spring preloaded structure to achieve tight contact with the ball for sealing. This design delivers low operating torque and stable sealing performance, which can significantly extend valve service life.
3. Multiple body material options are available for customization, suitable for water, steam, oil products, liquefied petroleum gas, natural gas, coal gas, nitric acid, oxidizing agents, urea and other process media.
4. It has a wide range of applications and is commonly used in various industrial working conditions that require tight shut off of pipeline medium flow.
Features & Benefits
1. The valve body is manufactured of premium grade material and equipped with ball test port. The middle body flange and valve neck adopt bolted connection construction.
2. The seats feature bidirectional single piston effect for upstream and downstream, providing Double Block and Bleed (DBB) function.
3. Three sealing configurations are available between seat and ball：standard soft seat sealing, triangular ring sealing and metal to metal hard sealing.
4. The stem incorporates anti blow out safety structure to prevent stem ejection caused by medium pressure under mis operation.
5. Fire safe and anti static structures are supplied as standard.
6. Emergency grease injection ports are reserved for both seat sealing and stem sealing. On line grease replenishment maintenance is available in case of leakage. Each grease injection port is fitted with grease injector check valve assembly.
7. The body is furnished with drain and vent ports：bottom drain valve is for cavity residual medium discharge and pressure relief; top vent valve is for cavity purging and cleaning.
8. The valve is compatible with various actuators, including manual, electric and hydraulic actuators.
9. For butt weld end valves, body material can be customized to match piping material for reliable welding performance. Extended sleeves prevent sealing components from damage during welding work.
10. Valves dedicated for buried service are fitted with extended stem for ground level operation. Grease injection, drain and vent assemblies are all operable from ground, and stem height can be customized upon request.
