FAQ

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

Gate valve DN65 what does that mean?: DN65 indicates that the valve bore is 65CM.The gate (gate valve) is a headstock ram, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed doors, discomfort pumpsparameters vary, usually 5 degrees is not high, medium temperature is 2 degrees 52'. To improve its manufacturability, make up for the deviation of the angle of the sealing surface during processing. This gate is called an elastic ram.

Gate valve Z41H-16Q generally used for what place?: Gate valve is one of the most commonly used cut-off valve, mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Suitable for medium and large diameter pipelines.

What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?: Cast steel flanged gate valve 25 pressure bore 250

What is the difference between the copper gate valve and the ordinary material gate valve?!: The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.

What is the allowable leakage rate of the gate valve D?: In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.

Does the relief valve have a gate valve?: With the ball valve, needle valve, with the valve did not see, but there should be some.

Is the axial force and torque of the wedge gate valve the same?: B higher temperature. C nice wedge single gate valve is suitable for high temperature medium easy to coking. Flexible gate valve features: high temperature, a wedge type single gate valve in a special form. Comparison with wedge gate valve.
