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:HVAC design, why is less than DN50 of pipe gate valve and cut-off valve,
It's not the valve! But the price relationship!
Q:What do you mean by "2" and "200 CF8M"?
CF8M is stainless steel, and 2 is caliber 50200 and should also be bore
Q:What is the difference between gate valve and gate valve? Is it the same valve?
The valve is driven by the valve stem to make vertical lifting of the plate inside the valve body.Gate valve is the same reason. The gate valve and gate valve have steel gate, parallel double gate and so on.So the gate valve and gate valve are the same valve. It's just a different name.
Q:What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?
Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
2, soft sealing gate valve at the bottom of the pit. No accumulation of slag material, valve opening and closing of the failure rate is low;
Q:Is the gate valve clockwise or closed?
In general, the valve is clockwise to turn off. Some of the clockwise rotation of the valve on the move is open
Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
9- electric (drive)4- flange connection (connection)1- plain wedge single gate valve (valve structure)H-Cr stainless steel (sealing surface material)25- nominal pressure is 25 kg, or 2.5MPa;DN250- valve by 250mm
Q:Gate valve z41t what does that mean?
According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy
Q:What kind of gate valve is Z6CS-H102?
Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr
Q:What are the working principles of the electric gate valve?
You see what type of electric valve, is integral or ordinary type, if the overall type Denso took power on the line, is generally 380V and 220V power supply, and then according to their own needs and then open the signal line, in place and closing in place and remote control line, valve position feedback signal 4~20ma over torque protection, fault signal. Ordinary type electric valve should be equipped with the control box, the motor is the true story and the inversion, and in general to a trip signal signal is normally open and normally closed, closed in place are normally open and normally closed two points according to their own needs wiring, three lines and then open and close control of the line of control there are also 4 lines to control some manufacturers, as well as the valve position, some three lines connected with the potentiometer, some installed valve position transmitter is connected with two lines, and over torque protection fault signal.
We focuses on supplying special valves applied to long-distance pipelines, petroluem, petrochemical processing devices and other harsh working conditions.We offer integrated solutions for industrial valves.The leading products of group are ball valve series, control valve series, cryogenic valve series, high temp.& pressure valve series, special material and process valves series.
