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 is the difference between gate valves Z41W-16R and Z41W-16P?: According to JB/T308P stands for Cr-Ni stainless steelR stands for Cr-Ni-Mo stainless steelCr-Ni stainless acid resistant steel has CF8, CF3, F304, F304L, which applies to the medium of work, such as nitric acid oxidation acid.Cr-Ni-Mo stainless acid resistant steel has CF8M, CF3M, F316 and F316L, which is suitable for working medium, such as acetic acid and reducing acid.

Q:How about the model of stainless steel gate valve?: Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.

Q:Installation and operation instructions of knife gate valve: 1. knife gate valve installation, check the valve cavity and sealing surface and other parts, not allowed to dirt or sand adhesion;2. bolts of connecting parts must be tightened evenly;

Q:How to distinguish between gate valve and cut-off valve?: Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!

Q:What is wire feed gate valve? What do you say in French?: Point to the wire gate valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common wayThe main difference is the connection

Q:Why does the centrifugal pump start and stop in the case of closing the gate valve?: Centrifugal pump to close the gate valve in the case of the start: the centrifugal pump power increases with its flow rate, when the flow is zero (valve closed), the minimum power to operate. Start the valve off from the angle of the motor. If the valve is started, the motor itself to start the current is larger, coupled with the power of the pump is also large, easy to cause the motor over-current trip, serious will burn the motor.

Q:What is the gate valve for the DN65 hydrant?: DN65 hydrants are available with either DN65 gate valves or butterfly valves.

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
