Q:greater than DN50 of the pipeline butterfly valve?: Heating butterfly valve is flanged connection. Pressure capacity is stronger than gate valve and stop valve. For connection safety, do not use gate valve and stop valve wire connection

Q:Which is the most expensive, check valve and gate valve?: In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124

Q:Yes, soft sealing gate valve can reach 25 kilograms, Fujian light valve company has this type of soft sealing gate valveAnonymous browsing | 28 times: Soft seal butterfly valve seal is good, but can only withstand up to 16 pressure, or the plastic can not stand. A short period of time is OK, and it's also related to the workmanship and quality of the factory. The quality is poor.

Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?: Cast steel flanged gate valve 25 pressure bore 250

Q:What do you mean by "2" and "200 CF8M"?: CF8M is 316,2 "is 50200 caliber stainless steel pressure (American Standard, LB)

Q:Why does the centrifugal pump start and stop in the case of closing the gate valve?: After the valve is closed to stop the cause of centrifugal pump outlet valve is closed to stop the pump to prevent the flow back into the pump, impeller, impeller in reverse, part of the mechanical seal in the pump pump impeller reversal will have adverse consequences, serious damage to the centrifugal pump, to close the valve after the shutdown.

Q:Does the relief valve have a gate valve?: No The front end must be in control.

Q:What does gate valve Z44T-10-200 code mean?: The meaning of the model is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionHttp://wenku.baidu /view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200

Q:What else, P54140V, 170V? What do they mean?: P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar

Q:What is the difference between Z41X gate valve and Z45X gate valve?: All flange soft sealing gate valve, but 41X is Ming bar, 45X is dark pole
