- Q: Butterfly valve use
- On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear.
- Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
- This butterfly valve in our factory called butterfly, 4 represents the connection of the flange connection flange is French, 41 in 1 on behalf of butterfly valve, W represents the body seal, is C that is actually the correct type of cast steel, should be D41W-1C. Suitable for ventilation, smoke, and these media.
- Q: What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
- 1, the drive mode is different (handle or turbine), mainly based on the size of the valve and the opening and closing torque to decide.2. The butterfly plate of the worm valve is installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees ~90 degrees between, when rotates to 90 degrees, the valve opens the card completely.3, clip type butterfly valve is to use double headed bolts to connect the valve between the two pipe flanges, flange butterfly valve is a valve with a flange, bolt with the valve flange at both ends connected to the pipe flange.
- Q: Butterfly valve flow direction is single or two-way?
- Hello, soft sealing butterfly valve is generally two-way flow, large bore with flow direction is one-way flow. Hard sealed butterfly valves are the same.
- Q: 1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.
- if your sure its not the thermostat than the zone valve should be near the boiler in the copper line. Most valves have a flat lever that slides when it is powered up to open. You can open manually by sliding the lever
- Q: Check valve; flexible joint `; installation order of electric butterfly valve
- It is better to make an elastic hanger.In order to prevent the generation of water hammer when the pump stops the damage to the rubber head, should be immediately set rubber head pump outlet, the gate valve and the check valve is not a very convincing reason to decide the order, custom order rubber head, check valve, electric butterfly valve.
- Q: Butterfly valve general use occasions
- Valve is especially suitable for low differential pressure, large diameter, large flow of gas and slurry liquid. For general control valve, DN300mm is big valve, only individual to DN450, and for the butterfly valve, DN500 below is a small valve, DN500 ~ 1000 is the standard valve, the largest butterfly caliber up to 9m. Visible, large diameter pipe with the main butterfly valve.
- Q: What does the butterfly valve D361H - 25C DN350 mean?
- Welded turbine butterfly valve, hard seal, material: cast steel, pressure 25KG, caliber 350MM
- Q: What does the butterfly valve model d344h, d345h, d346h, d347h mean?
- According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!
- Q: Fire signal butterfly valve what role?
- Signal butterfly valve should be human action monitoring alarm, once closed, that is, to the system alarmYou ask the two time, I answer two times, you give two points
