Q341H/Y hard seal ball valve

Q341H/Y hard seal ball valve

Hard seal ball valve adopts the single slope elastic sealing ring or V groove elastic sealing ring structure design, when medium pressure is too small, sealing ring and ball contact area is lesser, reason has larger sealing pressure, ensure reliable sealing medium pressure, sealing ring and ball contact area increases, so the sealing ring can be larger medium thrust without damage. Because the seal materials such as ptfe ethylene has good self-lubrication, with the sphere of the friction loss is small, so the ball valve of long service life.
