1.Technical Date:

Size: DN32-DN3000

Nominal Pressure: PN10/PN16

Operation Temperature: -15°C~115°C

Suitable Medium:

Air, compressed air, water, sea water, hot water, oil, acid, alkali, etc.

2.Feature

In a flexible rubber joint, pipes, also known as shock absorber shock absorber, suspension throat, soft joints, etc., is a kind of high elasticity, high air tightness, medium resistance and weatherability of pipe joint and its performance characteristics are:

1, small volume, light weight, good elasticity, easy installation and maintenance.

2, the installation time can produce transverse, axial, angular displacement, pipe impassability heart, flange unparallel restrictions.

3, the structure of the work can reduce the noise, vibration absorbing ability.

4, the seamless high pressure rubber joint, in the high temperature resistant, acid and alkali resistant, oil resistant more effectively prevent the corrosive medium in the pipeline for rubber joint lining erosion, improve the service life. Using range: because in a flexible rubber joint has good comprehensive performance, so it is widely used in chemical industry, building, water supply, water drainage, oil, light and heavy industry, freezing, sanitary, plumbing, fire protection, electric power and other infrastructure.

Q:Where is the Shanghai valve? What brand is good?: A lot of Shanghai brand brand of Shanghai KaiWeiXi, Department of finance the Kemei high Lidun Shanghai Karon these are good

Q:Valve connections - two how do different connections work?: The inlet and outlet of valve are respectively connected in two different ways: one end adopts flange connection, the other end adopts thread or socket.

Q:Who knows which kind of water valve is good?: Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.

Q:There is a rectangular hole in the valve core, which the heating company repairman gives to the bolt. Rest assured, I do not want to heating, but my indoor temperature is low, I suspect that the repairman mischief, deliberately give me lower temperature: The valve has a device resembling a cylinder lock without a dedicated key. However, your home heating is not hot, the valve does not have much relationship. As long as the hole on the valve is parallel to the pipe, the valve is fully open.

Q:Name: valve actuatorFunction: control valve switch by controlling air flow sizeIntended classification commodity code: 8412310090 (other linear acting pneumatic power unit, pressure cylinder)Shanghai Pudong Airport customs change classification: 84123900 (other pneumatic power unit)Commodity code information given by China Customs official network: 8412310090 (actuator, valve parts, valve actuation, pneumatic)Our goods encoding 8412310090 is classified to the Shanghai Pudong Airport customs dismissed, there are no friends of this commodity encoding on the official website of the detailed specifications defined, I Secretary in accordance with the valve function into 8412310090 encoding. Thank you: Various types of valves, with the continuous improvement of various types of equipment, process, the types of valves are still increasing. But generally speaking, they can be divided into two major groups.(1) automatic valve. A valve that moves by itself depending on the capacity of a medium (liquid, air, steam, etc.). Such as safety valve, pressure reducing valve, check valve, steam trap, air trap, emergency shut-off valve and so on. (2) drive valve. A valve operated by hand, power, hydraulic, or pneumatic. Such as gate valve, globe valve, throttle valve, regulating valve, butterfly valve, ball valve, plug valve and so on.

Q:What is the valve before and after the pump?: General pump should be installed before and after the pressure regulating valve, pump installed before the pressure drop valve, pump installed after the pressure regulator valve!

Q:What does the "PN" mark on the valve mean?: The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)

Q:What is the KVS in the valve parameter?: The valve Kvs is to reflect the passing capacity of the valve, which is defined as the pressure at both ends is 1bar, through the flow of the valve, Kvs is a characteristic parameter of the valve, and valve structure, is a constant value.

Q:Which direction is the valve? Which direction is it?: Generally: clockwise, counterclockwise, looseYou can also see the logo on the spool
