Non rising stem Protective Gate Valve
Product overview
The opening and closing part of the soft seal gate valve is the gate plate. The movement direction of the gate plate 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 model gate valve form a wedge shape. The wedge angle varies with the valve parameters. The nominal diameter is DN50~DN1200, and the operating temperature is ≤120℃. The gate plate of the soft-sealing gate valve is integrally lined with rubber, and the rubber deformation compensation function ensures a tight seal and no leakage. The product has a wide range of applications and can be used on pipelines under various working conditions in metallurgy, coal, electric power, petroleum, chemicals, pharmaceuticals, environmental protection, water treatment and other industries with working temperatures of -20~120°C to cut off or connect pipeline media.
Product Description
The resilient seated gate valves by introducing European high-tech valve manufacturing technology achieves good sealing effect and using the compensation effect of resilient deformation caused by the overall rubber coating of the gate, and overcomes the phenomena of poor sealing, water leakage and rust of general gate valves, lt can be widely used as requlating and intercepting devices on fluid pipelines such as tap water, sewage, construction, petroleum, chemical industry, food, medicine, light textile, electric power, ship building, metallurgy, energy system, etc.
Product Specifications
Features
Light weight: The body is made of high-grade ductile black cast iron, which is about 20% to 30% lighter than traditional gate valves and is easy to install and maintain.
Flat-bottomed gate seat: Traditional gate valves often have foreign objects such as stones, wood blocks, cement, iron filings, debris, etc. accumulated in the groove at the bottom of the valve after the pipe is washed with water, which can easily lead to leakage due to inability to close tightly. The bottom of the elastic seat seal gate valve adopts the same flat bottom design as the water pipe machine, which is not easy to cause debris accumulation and allows the fluid to flow smoothly.
Overall rubber coating: The gate uses high-quality rubber for the overall inner and outer coating. Europe's first-class rubber vulcanization technology enables the vulcanized gate to ensure precise geometric dimensions, and the rubber and ductile cast gate are firmly connected and are not easy to fall off and Good elastic memory. water
Precision cast valve body: The valve body is precision cast, and the precise geometric dimensions ensure the sealing of the valve without any finishing work inside the valve body.
