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.

Q:GB 300 gate valve, a multi?
GB DN300 flanged gate valve, PN10 manual 245kg bevel gear 315Other pressure levels, please specify specific pressure.Wenzhou Chaoda group Agel Ecommerce Ltd to provide the answer:
Q:What is gate valve (with force transfer joint)?
Double flange loose dowel joint is composed of telescopic joint and pipe flange, screw force transmission component, it can transfer the pressure thrust of the connecting piece (blind plate force) and error compensation line, cannot absorb axial displacement. Broad water supply, I hope to help you!
Q:Gate valve z11h/y-16 what does that mean?
Product Name: internal thread gate valveItem number: Z11HProduct specification: DN15-50Product pressure: 1.6MPa-2.5MPaMaterial: cast iron, cast steel, stainless steelInternal thread gate valve nominal pressure 2.5Mpa, applicable temperature range -20-232-350, applicable medium: water, oil, gas and certain corrosive liquid (W.O.G), thread type G.NPT.BSPT.BSP.DIN259/2999.
Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
Cast steel flanged gate valve 25 pressure bore 250
Q:What is the difference between gate valve and gate valve? Is it the same valve?
The same, very few people call gate valve, all call gate valve.
Q:What type of flange does it fit with the gate valve?
This depends on the type of gate valve, valve standards are marked with matching flange standards. Different types of flanges for different gate valves are also different.The flange of General GB gate valve is GB/T9113 series.
Q:What are the common standards for gate valves?
Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The following common standards for Fujian Biaoguang valve for valve: design specification: JB/T 7746, API602 JB/T 7746, the length of the structure specification / thread socket factory test and inspection of JB/T1751/GB7306, ANSI: B16.11/B2.1: JB/T 9092, API598 pressure temperature: GB/T 9131, ANSI B16.34, MSS GB/T 12220 product ID: SP25 delivery specification: JB/T 7928
Q:What are the advantages and disadvantages of flat gate valves?
The advantage of flat gate valve is that the flow resistance is small, and the flow resistance is similar to the flow resistance of short valve. The flat gate valve with guide hole is installed on the pipeline and can be directly cleaned with the cleaner. As the gate is sliding on the two seat surface, the flat gate valve can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually positioned automatically. The seat seal surface is not subject to thermal deformation of the valve body. Moreover, even if the valve is closed in cold condition, the thermal elongation of the stem will not cause the seal to be subjected to overload. The length of the structure is much shorter than that of the ball valve, and it is easier to start. Light plate gate valve is more refined, but the effect is exactly the same.The disadvantage of flat gate valve is that when the medium pressure is low, the sealing force of the metal sealing surface is insufficient, so as to achieve satisfactory sealing. On the contrary, when the medium pressure is high, if the sealing surface is not lubricated by the system media or foreign media, often opening and closing may cause the sealing surface to wear too much. Another disadvantage is that the circular motion of the circular gate in the circular flow, only when it is at the valve closed position of 50%, this valve is more sensitive to flow control. Moreover, the gate will produce severe vibration when it breaks the high-speed and dense medium flow. The valve seat can also be throttled if the seat is made of a V - shaped opening and is tightly oriented to the gate.
Q:Generally, how big is the diameter of the installation flange plate gate valve?
Under normal circumstances:Flanged gate valves for piping over DN50,DN50 (below) can be made of wire or gate valves, or flanged gate valves (flanged valves or welded gate valves)
Q:How about the model of stainless steel gate valve?
Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.
