GATE VALVE NON-RISING STEM RESILIENT SOFT SEATED DUCTILE IRON DIN3352 F4 DN40-DN800

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 are the specifications of the gate valves? Does the work pressure need to be marked separately?: Gate valve code Z, such as GB gate valve Z41H-16. Front is the valve type, and the back 16 represents the pressure of 16 kg, 1.6MPa

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: 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: Z41T one 10 gate valve and Z44T one, 10 gate valve difference: Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa

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: Is the gate valve flanged?: The most commonly used gate valves are threaded connections, flanged connections, and welded connections.Like the outer thread connection, the clamp connection, the card sleeve is seldom used.

Q: What is the wedge type gate valve wedge is what mean: According to the gate can be divided into the form of parallel wedge type. (1) wedge type gate. Wedge type gate the sealing surface of a certain angle with the vertical center line of the gate, the size of angle depends on the medium temperature and diameter size. General medium temperature is higher, and the greater the inclination angle is bigger, in order to prevent the temperature change when the gate is stuck, unable to open. Wedge gate sealing than the parallel well.

Q: The main question is, what are the functional differences in which case?: The gate (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 valve. The 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 valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex
