In storage tank operations, zero leakage must be achieved when the valve is closed, otherwise the medium in the storage tank may be contaminated, which may cause serious economic losses or safety accidents.


However, when the medium water level in the storage tank is low, the pipeline pressure is very low, and the piston effect sealing of traditional ball valves is difficult to achieve, and leakage occurs. At the same time, these valves operate extremely frequently, and they are also prone to aggravate leakage due to the wear of the sealing surface.


"Cool Seal" Y series DBB forced sealing ball valve is a two-way forced sealing upstream and downstream. It does not rely on system pressure. It can easily achieve "blind plate" sealing and truly achieve zero leakage. The built-in DBB function can instantly detect the integrity of the seal. sex.


The ball of "Cool Seal" Y series DBB forced sealing ball valve adopts frictionless rotation design, which will not leak due to the wear of the sealing surface. It is very suitable for frequent operation and has a long service life.


The full-diameter design of "Cool Seal" Y series DBB forced sealing ball valve has the best flow field and Cv value, which greatly reduces the energy and pressure loss through the valve flow path, and can complete the medium transportation more efficiently.


In addition, the valve stem of the "Cool Seal" Y series DBB forced-sealing ball valve is quarter-turn operation, which is essentially different from the lift-rod design in terms of sealing stability. Its switch only needs more than 200 degrees of valve stem angular stroke operation and the operating torque is extremely low, which can save the user's investment in the actuator.
