Product Description:

Gate Valve

 

Flange ends cast steel gate valve are used to cut or connect the pipe media under nominal pressure between class150-2500, working temperature≤600°C, in oil industry, chemical industry, fossil-field power plants.

Design Feature

1. Both design and manufacture are carry out strictly fellow API600 and API602. The products feature a reasonable structure, reliable seal, good performance and nice modeling.

2. Co hard alloy welded sealing surface, which is wearing resistance, erosion proof, abrasion proof and long-lived.

3. The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistance.

4. Class≥900LB, the media 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.

5. There is backward sealing structure in the valve, so the sealing is reliable.

6. The material of the filling and the flange size can be chosen and the matched according to the applications and the requirement of the wier's. That can satisfy all kinds of working requirements.

Q:Fire protection gate valve from the wall how many distance there is no regulation?
Don't know don't answer. "According to the provisions of article 6.2.13 GB50038-2005" code for design of basement for civil air defense engineering, into or through the door unit between the door closed wall should be set up in the inner side or two nominal pressure pipeline is not less than 1.0MPa, the spool is stainless steel or copper gate or globe valve water pipe from the air enclosure structure. The installation position from the wall should be not more than 200mm.
Q:What is the difference between an elastic gate valve and a rigid gate?
Brief introduction: the valve gate valve is a gate 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. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'.Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.
Q:Why is gate valve or butterfly valve used for water pump?
General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
Q:The difference and use of gate valve and 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.Minor force needed for opening and closing.
Q:Which is more expensive, bronze gate valve or brass gate valve?
The casting and workability of brass are much better than that of stainless steel, especially the valve with more complicated internal cavity.
Q:What does gate z41t-10 150 mean?
According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
Q:What valve is z45w gate valve?
Cast iron gate valve with turbine head, please contact me
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.
Q:Analysis of the advantages of elastic seat sealing gate valve?
When the elastic seat sealing gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the flashboard is pressed to the valve seat of the other side only by the medium pressure to ensure the sealing of the sealing surface, which is self sealing.
Q:What does "Z45W-10T" mean?What does each letter stand for?
T is the material code for the valve body, which stands for copper and copper alloysZ45W-10T, which means manual, flange connections, dark wedge rigid single gate plate, the valve seat sealing surface material directly processed by the valve body, nominal pressure PN10, valve body material for Brass Gate Valve
