Z45X Non-rising resilient seat gate valve
This High quality 4 inch resilient seated ductile iron gate 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.
1.Such a design as the dustproof ring plus three layers of o-seal ring makes the sealing
reliable and on-line replaceable.
2.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.
3.The gate is wrapped with rubber,anti-corrosion and good at tightness.
4.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 1.5times of PN and for low pressure sealing under 0.02Mpa.
