Q: What is the soft seal gate valve?: Cautions for installation and maintenance of soft sealing gate valve:For double gate valves, the direction of installation shall be in the vertical position of the valve stem, and the handwheel at the top.The installation of the soft gate valve shall be carried out in strict accordance with the installation environment, installation conditions and installation procedures on the factory manual.After installation, the soft seal gate shall be periodically checked for performance and killed in the cradle before any undesirable conditions occur.

Q: How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.: Flanges for piping above DN50,DN50 (below) can be made of wire or flange (flange for pressure piping)

Q: Why? God, can you explain to me in detail why?: The exit of the general pump is the first soft connection (shock absorber), followed by the check valve, and then the partition valve (such as butterfly valve, gate valve, cut-off valve, etc.), this is not the final answer.The question is interesting, and no corresponding information has been found in the relevant standards. We have also discussed the related issues, but differences of opinion is relatively large, the advantages of 1, first installed check valve installed after the valve or butterfly valve, check valve, can be protected, especially in a parallel pump, when the pump does not start, another pump starts when the impact force is gate valve or butterfly valve bear, disadvantages: gate valve or check valve who will protect? There have been a case of butterfly valve is broken. 2, first installed gate valve or butterfly valve installed after the check valve, advantages: can protect the butterfly valve or gate valve, the impact on the check valve to bear. Disadvantages: check valve who will protect, check valve by pressure difference switch, if the high pressure high pressure pipe, pump, if the flow is not stable, so check valve will repeatedly switch, will affect the check valve life. Personal opinion: check valve, check valve performance now have changed, many are using the slow closing check valve, so the impact force is two aspects to bear, because exports are not fully open the valve or butterfly valve, so you can put in check after the gate valve or butterfly valve valve. If not the slow closing check valve installed in the valve or the best after the butterfly.

Q: Is the gate valve clockwise or closed?: Usually it's off. There are some special occasions. It is said that the plane uses a lot of counter

Q: What is the wedge type gate valve wedge is what mean: According to the gate can be divided into the form of parallel wedge type. (1) wedge type gate. Wedge type gate the sealing surface of a certain angle with the vertical center line of the gate, the size of angle depends on the medium temperature and diameter size. General medium temperature is higher, and the greater the inclination angle is bigger, in order to prevent the temperature change when the gate is stuck, unable to open. Wedge gate sealing than the parallel well.

Q: Internal screw current limiting gate valve (Tan Gang) PN5.0 DN15/ Phi 1 Rc1/2 what does that mean?: We did thatInternal thread current limiting gate valve (Tan Gang)Body material: carbon steelPressure rating: PN5.0 = 300LB American StandardNominal = DN15 = 1/2"Phi 1 = in the middle of the gate drilling a Phi 1 hole, so that in closing there will be a certain flow, that is, the minimum flow, that is, the current limit.Rc1/2 is thread, which is the connection

Q: What's the difference between a soft seal gate valve and a hard sealed gate valve?: The difference is that the form of the gate seal surface is different.General gate valves are generally leaking, easy to rust and other phenomena. Soft sealing gate valve (elastic seat sealing gate valve), gate material for cast iron lining rubber, overcome the shortcomings of the general gate valve, such as poor sealing, elastic fatigue, easy to rust, etc.. Soft sealing gate valve is a new product of the traditional gate valve.

Q: What is the gate valve for the DN65 hydrant?: DN150, of course. Ask me about fire protection

Q: Is the axial force and torque of the wedge gate valve the same?: B higher temperature. C nice wedge single gate valve is suitable for high temperature medium easy to coking. Flexible gate valve features: high temperature, a wedge type single gate valve in a special form. Comparison with wedge gate valve.

Q: Acid resistant alkali valve gate valve: Fluorine gate valve; material: carbon steel, cast iron; design standards: JB, GB, ANSI, BS, API, ISO, DIN, NFZ, lining valve;
