The Z545X manual umbrella gear non raising stem elastic large diameter gate valve can be easily opened and closed with a spiral umbrella gear mechanism installed by one person,gate plate has interchangeable function. It can be equipped with opening and closing indicator columns or electric or pneumatic actuators according to user requirements. Excellent sealing and rust prevention functions, safe and reliable, with a long service life. Can be installed vertically or horizontally. Large diameter gate valves are widely used in water supply and drainage systems, sewage treatment systems, municipal construction, mining, metallurgy, power plants and other industries.
Application scope: Used as a regulating and intercepting device on fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electricity, ships, metallurgy, energy systems etc.
Product features:
- Integrated valve cover non raising stem design, compact structure; The valve stem nut and gate plate have a two body structure, with no jamming phenomenon and a straight channel and no leakage or concave cavity; The valve stem is sealed with an O-ring.
- It has excellent anti-corrosion performance, with epoxy resin sprayed on the inner and outer surfaces of the shell,when necessary, the inner surface is lined with enamel, and the connecting bolts are made of hexagonal bolts with top sealing.
- Reliable and hygienic epoxy resin meets the hygiene standard GB/T17219-1998, and the overall coating of the gate meets the hygiene inspection of rubber; The valve stem, valve stem nut and other components are made of stainless steel or bronze materials that are not corroded by water.
- Suitable for industries such as drinking water, water supply and drainage, sewage treatment, natural gas and gas, industry and food.
Execution standards: Design and manufacturing: GB12234-89 Structural length: GB12221-89 Flange size: JB/T79-94 Valve inspection and testing: GB13927
