The housing is fitted with a ring seal (7) having on its underside a first sealing lip (8) which with low closing pressure completely adjoins the ball so that the channel is tightly closed. Above the first lip the seal has a second sealing lip (9) against which the ball is supported...
Ball valves operate by opening to allow flow or closing to shut-off flow within a pipeline by way of a fitted ball inside the valve body with PTFE seats. Through the floating position of the ball, in closed position a movement into the flow direction becomes possible providing for optimum ...
Dervos Valves is a professional industrial valve manufacturers,specializes in electric and manual valves,including ball valves,gate valves,butterfly valves,check valves and other special pipe valves,also offer best purchasing suggest.
6. In the fully open or fully closed state, the valve body and seat sealing surface and the dielectric isolation, medium-through, do not cause the valve sealing surface erosion. 7. The applicable scope is wide, ranging from small to several millimeters to lar...
The handle lies flat in alignment with the flow when open and is perpendicular to it when closed, making for easy visual confirmation of the valve's status. Ball valves are durable, performing well after many cycles, and reliable, closing securely even after...
1. Working Principle The core structure of a plug valve is a cylindrical or conical plug with a through passage. When the plug rotates, the passage aligns or misaligns with the fluid pathway of the valve body, thus controlling the opening and closing of the valve. (1) Open Position When...
Ball valve for diesel fuel is completely open and ball valve for vegetable oil is completely closed in initial position. Both are connected to ball valve by control lever and linkage. Stepless control actuates baud train. This control could also be effected over gear wheels on ball valve and ...
Opening valve time: 10~120 seconds( adjust) Quick closing time: 1.5~30 seconds(adjust) Slow closing time: 6~120 seconds(adjust) Fast close angle: 70° ± 10° Slow close angle: 20° ± 10° Open state minimum flow resistance coefficient: 0.1 Optional control power:...
The double eccentric structure is located in the ball storage chamber when opening, with a large flow cross-section, and the valve is not washed out. When closing, the valve core is not washed out. When opening, the spherical surface of the valve core gra...
The completely equal valve body cavity provides a small resistance and straight flow path for the medium.It is generally believed that ball valves are most suitable for direct opening and closing use, but recent developments have designed them to have throttling and flow con...
