Body And Bonnet Connection Of Cast Steel Flanged Gate Valves


The body and bonnet of Class 150-Class 800 globe valves are usually with studs and nuts,And the body and bonnet of Class 1500-Class 2000 globe valves are usually of pressurized seal design.


Back Seating Design Of Cast Steel Flanged Gate Valves:


All our globe valves have the back seating design. In most cases, the carbon steel globe valves is fitted with a renewable back seat. For stainless steel globe valve, the back seat is machined directly in the bonnet or is machined after welding. When the globe valve is at fully open position, the sealing of the back seat can be very reliable. However, as per the requirement of API 600, it is not advisable to add or change packing by the mean of back seating when the valve is pressure containing

Design Feature Of Cast Steel Flanged Gate Valves


Rational structure, reliable sealing, excellent performance, pretty appearance.

Co-radix alloy welded sealing surface, anti-wearing, erosion-proof abrasion-proof and longer use life.

The surface and the adjusting media of the valve shaft are nitrogenzed so that it is erosion and abrasion resistant.

Class1500,the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure the sealing performance.

There is no backward sealing structure in the valve, so the sealing is reliable.

The material of the filling and the flange size can be chosen and matched according to the applications and the requirements of the wier/s. That can satisfies all kinds of working requirements




Packaging & Delivery Of Cast Steel Flanged Gate Valves


Molded flexible graphite is used for packing material. PTFE or combined packing material can be also used if being requested by the customer. The internal surface of the stuffing box, of which area is contacted with the packing, is of excellent finish(Ra 3.2µm). The stem surface, contacting with the packing, should be rolled and pressed after being precisely machined, so as to reach to the high finish and compactness (Ra 0.8µm) and ensure the reliable tightness of the stem area.


Usage/Applications Of Cast Steel Flanged Gate Valves:



These products are widely used in water source projects, urban water supply and drainage, sewage treatment, electric power, petroleum, petrochemical, heat supply, shipbuilding, medicine and metallurgy industries.

Valves are used for regulating or cutting off liquids in pipelines. Liquids available include water, sewage, sea water, air, foodstuff and oil.
