Q: Standard and specification for pressure test of valves: (11) when the valve with drive device is tested and its tightness is tested, the sealing test shall be carried out by using the driving device to close the valve. For manual drive units, seal test shall also be done with the actuating closing valve.(12) the by-pass valve installed on the main valve after the strength test and the sealing test. The strength and tightness test of the main valve is carried out. The main valve should be opened when the closing member is opened.(13) iron valve strength test, the application of Pratia tapping valve and valve cover, check whether there is any leakage.(14) the valve test, in addition to the provisions of the plug valve to allow sealing surface oiling, other valves are not allowed in the sealing surface of the oil test.(15) when the valve pressure test, the blind plate on the valve pressure should not be too large, so as to avoid deformation of the valve, affecting the test results (cast iron valve if pressed too tight, will be damaged).(16) after the valve test pressure, should promptly remove the water and clean the valve, should also be prepared for the test record.

Q: What is the difference between valve j941H-40 and j41H-40?: Valve design manual showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)According to the comparison, we can see that the difference is that one drive mode is electric, one is transmission mode, and the other is manual. What do not understand, you can ask me directly. Two hundred and fourteen million two hundred and seventy-seven thousand eight hundred and fifty-one

Q: So how does the valve turn on?: The handle of the valve is opened along the pipe and perpendicular to the pipe

Q: Ketem valve relative to other valve companies in the industry what are the advantages?: Floating hard sealing electric ball valve is suitable for two cutting and adjusting occasions. Connect the valve and actuator by using direct connection, DCL series miniature electric actuator (also can be configured according to user requirements of the electric actuator or pneumatic piston actuator of different types of electronic components and ultra short ball).

Q: What does valve J41H-16C mean?: J- stop valve4- flange type connection1- structure typeH- alloy steel seal16- nominal pressure 16 kgC- body carbon steel

Q: How to quickly identify the types of valves?: You can look through shapes, signs, or buy a valve manual

Q: Air compressor out of the gas with what kind of valve control okay, globe valve or other?: What's the use of your air compressor? Is it manual or automatic? By the way, I think it's ok if the demand is not very strictWhat we used on board was the cut-off.

Q: The valve is rusty and can not be opened. What shall I do?: There are pictures, for different valves, then choose different ways of opening.

Q: If the valve in the pipeline throttle, such as open and open 50%, the valve before and after the pressure of how to calculate, how the flow changes?: The valve according to feature points, can be divided into isolation, cut off, check, overflow and regulation, which belongs to the regulation is more complex, such as for a compressible medium, constant flow regulating valve after the pressure is more and more big, natural gas pipelines are now part of the regulating valve the self,

Q: How are the types of valves classified?: Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion.
