Product Description

Check va es are mechanical va es that permit gases and liquids to flow in only
one direction, preventing process flow from reversing. They are classified as
one-way directional va es. Fluid flow in the desired direction opens the va e,
while backflow closes the va e. The mechanics of check va e operation are not
complicated. Most check va es contain a ball that sits freely above the seat,
which has only one through hole. The ball has a slightly larger diameter than that
of the through hole. When the pressure behind the seat exceeds that above the
ball, liquid is allowed to flow through the va e. Once the pressure above the ball
exceeds the pressure below the seat, the ball returns to rest in the seat, forming
a seal that prevents backflow. We manufacture check va es in conformity with
ASME B16.34 standards. All va es are tested according to API 589 requirements.
The marking is as per MSS SP-25 standards.
