Non Rising Resilient Seat gate Valve
Purpose
This valve is mounted on various pipelines and used as a bi-way closed circuit equipment for tap water, sewage treatment, metallurgy, petroleum, building, chemical, electric power etc. industries.
Features
- Such a design as the dustproof ring plus three layers of O-seal ring makes the sealing reliable and on-line replaceable.
- The design with an aluminum bronze bearing inlaid in the gate leaves a good self-lubrication and a high strength. The said bearing can be replaced without need to replace the integral gate when worn out after a long time use.
- The gate is wrapped with rubber, anti-corrosion and good at tightness.
Advanced surface treatment, coated with harmless epoxy resin static powder, anti-corrosion, non—pollution, can be used in a drinking pipeline.
The body is gate—slot free designed, the channel is smooth without causing impurities to be piled up, more suitable for sewage working condition.
- Reliable integral sealing, zero—leak for high pressure sealing under 1.5 times of PN and for low pressure sealing under 0.02MPa.
