Q:HH valve company in the United Kingdom, how about the valve?
Our factory boiler has this brand of valve, used for many years, has been no problem, really good.
Q:Valve pressure grade division
Nominal pressure PN is less than 1.6Mpa valve is low pressure valve, nominal pressure PN2.5 - 6.4MPa valve is the pressure valve, nominal pressure PN10.0 - 80.0MPa valve high pressure valve.
Q:Which valves are installed in a directional manner?
Depends on the specific valve is one-way seal or two-way seal?
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).
It looks a bit like the butt weld butterfly valve. The two sides are welded to the pipe. There is a step on either side of the valve. Overhead welding

Fisher (Emerson's brand, pneumatic head and regulating valve is good) mountain Wu (Japan's control valve is doing well)
Q:How to use current to control valve opening and closing?
You don't know if the precision requirement of high precision can be used for high requirements of valve control valve (4-20mA) control but need converter needs the temperature signal into your current signal control valve (4-20mA) valve door factory will not have this thing you can ask to do control system manufacturers (in tell you part of the valve switch and adjust the price of at least 1000 points (OH) to not give me angry) is something you can ask me the valve factory
Q:What are the main equipments for valve production?
I know these gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves, check valves, and throttle valves
Q:Why use the pump outlet valve to adjust the flow rate?
Adjust the speed of the water pump to adjust the flow of the most appropriate, such as liquid or variable frequency control, with the switch pump outlet door to adjust the flow rate is the most uneconomical.
