Q: What is the use of each brand in the super high-rise, commercial complex, hotel? Price comparison of each brand? In the general valve, balance valve, electric valve, who did the best? Any knowledge about the valve, please ~ ~ thank you for your generous with your criticism: Tyco doesn't know much about it. It's often written in the bidding documents, but there are very few actual purchases, so I don't evaluate it any more. The strongest of the balance valves is the TA (Swedish). He was the originator of the balancing valve. Super high-rise complex, the hotel part, you mention these kinds of valves are applied a lot.

Q: Valve connections - two how do different connections work?: The connection of two different connection forms is achieved by a transition conversion connector

Q: What do you mean by "P54" in the valve z962y-p54 100V?: Applicable temperature 540 degrees centigrade；Applicable temperature 540 degrees centigrade

Q: Air compressor out of the gas with what kind of valve control okay, globe valve or other?: Air compressor all copper safety valve (AQ-20) (AQ-25)Air compressor, air release valve and so on. The air compressor rated exhaust pressure is divided into low pressure (0.7~1.0MPa), medium pressure (1.0~10MPa), high pressure (10~100MPa) and ultra high pressure (100MPa or more), to see what kind of installation you are and use

Q: What does the "Z45T-16" valve mean?: Z - gate valve4 - flange connection5 - Dark pole, stem non lifting (gate valve structure)T - copper alloy, valve sealing face code16 - pressure code, 1.6MPaMaterial code for grey cast iron valves of nominal pressure less than or equal to PN16 shall be omitted in model preparation.May refer to JB/T 308 valve model compilation method

Q: The valve has a clear opening and closing sign. What does this sentence mean?: Not only on the valve is enough to mark, here means that at the scene can see the installation of the pipe network on the valve open or shut?!

Q: How to check if the gas valve is open?: The gas valve has a handle, and the handle is parallel to the pipe and is opened, and the vertical is closed. If there is no handle, there is a rectangular main handle on the valve, the principle is the same as above.

Q: What valve does the high pressure by-pass valve DN254 * 800 belong to?: High pressure bypass valve DN254 * 800 belongs to bypass valve.Function of bypass systemThe turbine by-pass device mainly has three functions of starting and overflowing:1 in the cold, warm and hot, the bypass system can realize the optimal unit start-up and shut-down in turbine operating conditions, start and stop curve can meet the requirements, two types of automatic and manual operation, with the establishment of the boiler steam temperature and steam turbine components. To shorten the start-up time.2. when the turbine is tripped, the bypass system can operate at a high speed and reach full open position.3., when the turbine load changes, the by-pass system has the regulating function, and the safety valve action can be avoided and the operation stability of the boiler can be improved when the instantaneous change of the moving state.The function of the bypass control valve:The main function of steam turbine bypass system is high pressure steam adjusting throttling and superheated steam cooling. The bypass valve to perform these functions at the same time and in low noise, small vibration, valve resistance to achieve its goal of temperature and pressure loss under the condition of touch.

Q: What do you mean by the 16 bit coding of the valve type?: What kind of coding do you mean? Valve type? Stress? Do you have these?Profit ZF43Y-250C-DN50.. Do you mean this one? ZF43Y valve type. Flat gate valve250C. Refers to the 250 pressure, C is carbon steel, DN50 refers to the caliber of the valve specificationsI hope you mean this one

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.

We have advanced technologies, facilities, resources and talented personnel for processing, developing, studying, designing and manufacturing of different kinds of valves.
