Cast Steel Flanged Gate Valves
Specifications Of Cast Steel Flanged Gate Valves:
Nominal Diameter: DN15~200mm
Nominal Pressure: 1.6MPa
Suitable Medium: water, steam, oil
Suitable Temperature: ≤100°C
Type of drive: hand lever, worm gear, electric
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.
Class≥1500,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:What is the difference between gate valve Z41T and Z45T?
- Z41T is a dark pole gate valve, and Z45T is a plain rod 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 is the gate valve for the DN65 hydrant?
- DN150, of course. Ask me about fire protection
- Q:The difference between cut-off valve and gate valve
- Structurally, the gate valve for the gate, down to the front and back seat seal; globe valve with spherical, taper and flat spool, down to the valve seat seal. Functional stop valves are generally used for pressure flow control. Gate valves are used for isolation.
- Q:what are their applicable conditions? Advantages and disadvantages?
- Butterfly valve is a disc type of open and close parts reciprocating reciprocating about 90 degrees to open, close and adjust the fluid channel of a valve.Advantages: the butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, and torque is small, simple and rapid operation, and also has good flow characteristics of regulation and sealed off, is nearly 10 years the fastest growing valve, high temperature and high pressure, and to large diameter, high sealing function of the direction, long life, good adjusting features and a valve development.Disadvantages: the butterfly valve relative to the gate, ball valve pressure loss is relatively large, it is suitable for pressure loss requirements lax piping system.Under normal circumstances, it is not suitable for high temperature and high pressure pipeline system.Valve is closed parts (valve) moving along the centerline of the valve seat, the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional to, is also very suitable for the regulation of traffic.Advantages: in the process of opening and closing, the friction between the disc and the valve body is smaller than that of the gate valve, so it is wearableThe opening height is generally only 1/4 of the diameter of the seat channel, so it is much smaller than the gate valveGenerally, there is only one sealing surface on the body and disc, so the manufacturing process is good and easy to maintain;Disadvantages: the flow resistance coefficient is relatively large, resulting in pressure lossUnsuitable for large caliber productionThe opening and closing moment is larger and the structure length is longer.
- Q:Please tell the specific specifications and specifications of the gate valve and advise the principle of management cooperation Thank you
- DN200 refers to the nominal diameter of the valve, the unit is mm, PN160 refers to the valve tolerance pressure, the unit is 1/10MPa.
- Q:Gate valve z45h-10dn250 length of the body?
- Z45h-10dn250 body length L=330mm, this valve is hidden bar, elastic seat, sealing gate valve, gate lining, lining fluorine, belong to soft seal
- Q:What is the difference between the copper gate valve and the ordinary material gate valve?!
- The material of general gate valve is cast iron, and the copper gate valve should be used in special requirement.
- Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
- Water supply and drainage and civil air defense works, now with the dark rod type elastic sealing gate valve more.Compared to the gate and the traditional carve type or parallel double gate plate valve has the following characteristics: 1, soft sealing valve body, valve cover using precision casting foundry, a molding, no mechanical processing, do not use sealed copper ring, saving non-ferrous metals;
- Q:What's the difference between the knife gate valve and the stop valve?
- Standard light valve professionals to answer for you, gate valve refers to the closure of parts (gate) along the central line of the vertical direction of moving valve. The gate valve is mainly used for cutting in the pipeline. The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.
