Hz series corrosion resistant stainless steel check
Product Overview
1.Check valve is mainly used to separate drilling liquid and fluid. It is installed inside the high pressure piping to prevent liquid backstreaming by self-closing baffle. It is manufactured in full conformance with API-6A Standard;
2.
High pressure check valve is composed by valve body, valve deck, valve seat and valve rod;
3.When the liquid flows along with the arrow direction, liquid will push the valve plate and open the valve and let the liquid in. on the contrary, valve plate will cover the valve seat and make it sealed.
Design Features
1.High structural strength:check valve is forged by high strength alloy steel;
2.Convenient assembling and disassembling: both end union joints contribute to easy assembling and disassembling of pipeline;
3.Good sealing performance: valve baffle is vulcanized by hydrogenation nitrile rubber buna on the surface;
4.Long life span: it has long life span under high pressure;
5.Convenient maintenance: no need to remove check valve from high pressure piping for routine maintenance;
6.Well environmental adaption: except for routine work high pressure check valve, we are also supplying check valve working under vulcanization environment.
