Product Description

The working principle of anti-theft stop valve:
locking valve according to the "rotation without leakage theory", the use of push and pull magnetic circuit optimization design scheme, the traditional valve opening and closing operation mechanical force into torque, by rotating the special handwheel, drive the shield of the inner magnetic yoke (and the valve stem is connected as one) rotation, complete the valve opening and closing. Because the opening and closing mechanism is closed inside the valve, the original dynamic seal (packing) is canceled, so the external leakage of the valve is fundamentally eliminated. Because there is no mechanical connection between the operating handwheel and the valve stem, the handwheel can be removed after the operation is completed. The unique technical structure makes the magnetic torque valve have the functions of zero leakage, anti-theft and self-locking.
Anti-theft stop valve Significant features:
anti-theft stop valve is based on the heating system on the use of units do not pay in time and oil field often caused by the loss of stolen oil time, and the development and design of successful valve products. Anti-theft stop valve has good anti-theft performance, can achieve zero leakage, easy switch, stable sealing effect, long service life and so on.
Anti-theft stop valve use method:
1, after the installation of anti-theft stop valve, take the accessory wrench, set in the top of the valve keyway to open (or close) the gate of the valve, clockwise close, counterclockwise open.
2, zero leakage: the application of "no leakage transmission technology", the opening and closing system is sealed inside the valve body, turn the special handwheel, complete the opening and closing operation of the valve, completely eliminate the leakage;
3, anti-theft: because the special handwheel and valve stem no mechanical connection, after the operation can be taken off the handwheel, can avoid misoperation and anti-theft role, easy to control, management; Second, the use of: After the installation of the anti-theft valve, take the small hexagonal screw on the upper end of the accessory wrench to turn out the small hex screw on the cover of the valve, remove the lid, the middle is the lock core, such as a key lock core to open with the key, such as a combination lock core (see the password preparation and use of anti-theft valve), after taking out the lock core, use the lower end of the accessory wrench to open (or close) the valve, clockwise off, counterclockwise open.
4, password lock: the use of magnetic field polarity, strength change and mechanical size design of different characteristics, can make the product has a "password lock" function, that is, the specified valve can only be opened with the specified handwheel, to achieve "one valve one key", "multiple valves one key";
5, long service life: because the valve to achieve full sealing mechanism, cancel the packing, reduce the valve stem wear, so that the valve opening and closing flexible, and will not show dead, extend the service life of the valve;
6, environmental protection and pollution-free: due to the elimination of leakage, changed the use of the site of the working environment, to solve the problem of on-site pollution, is a really green valve.
Anti-theft globe valve, the driving mode can be selected manual, worm gear, pneumatic, electric, connection mode can be selected flange, structural form can be selected anti-theft type, sealing structure can be selected soft seal, hard seal, pressure range PN0.1-10Mpa, nominal diameter of DN25-250mm, material can be selected cast steel, stainless steel. Because the use of the valve is very wide, the same kind of valve in different occasions and working conditions have different collocation, if you are non-professionals, welcome to the company to inquire. The company has professional and technical personnel for your service!
