Fire Fighting System Use Ductile Iron Rising Stem Resilient Seated Gate Valve
Product introduction:
Fire fighting valve products are control accessories on industrial and building pipelines. Fire fighting valve is the most important controlled accessory on industrial and building pipelines, normally consisting of valve body, opening and closing mechanism, and valve cover. Simple structure and reliable sealing.
Z81X series resilient seated soft seal gate valve is one of the most important and popular valve products used in fire fighting and water supply system industries. Its opening and closing component is the gate, and the direction of the gate's movement is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted or throttled.
Z81X series resilient seated soft seal gate valve is a replacement product of traditional gate valve, which utilizes the compensation effect of elastic gate plate to produce slight deformation and achieve good sealing effect. This valve has significant advantages such as lightweight switch, reliable sealing, good elastic memory, and long service life. It can be widely used in fluid pipelines such as tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems, etc.

Product features:
1. The bottom of the resilient seated soft seal gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris accumulation and makes the fluid unobstructed.
2. The resilient seated soft seal valve body is coated with powder epoxy resin, which can prevent corrosion and rust of the valve body and can be used in sewage systems.
3. High quality rubber is used for overall internal and external sealing. The rubber is firmly attached to the valve and is not easy to fall off.
4. The valve body adopts precision casting, and the precise geometric dimensions ensure the sealing of the valve without any precision machining inside the valve body.
5. The weight of ductile iron valve body is reduced by about 20% -30% compared to traditional gate valves. Easy installation and maintenance.
