PEEK valves offer many advantages over traditional seat valves, including improved performance in high-pressure and high-temperature applications. Additionally, PEEK valves are resistant to pitting and debris accumulation, making them desirable for applications where cleanliness is vital.
PEEK (polyether ketone) is an outstanding high-performance semi-crystalline engineering thermoplastic with exceptional resistance to harsh chemicals, deficient moisture absorption, good fire performance, excellent mechanical strength, and dimensional stability in a range of environments.
PEEK seat valves are ball valves that use a small, round seat that sits atop the valve body. This seat is press-fitted into the valve body and held in place by a small screw. When the user pushes down on the seat, it causes the ball to drop out of the hole in the seat and into the valve body. This allows for quick and easy flow adjustment.
Another benefit of PEEK valves is their ability to seal against both sides of the valve body. This prevents water from leaking out of either side of the valve, meaning less maintenance is required. Additionally, PEEK valves come in various sizes and shapes, making them compatible with multiple applications.
PEEK degrades relatively little during injection molding, which makes it an excellent choice for managing the dimensional tolerance range of injection-molded PEEK parts, which results in the dimensional accuracy of PEEK parts being much closer to that of available plastics than the dimensional accuracy of other plastics. Small coefficient of thermal expansion. The size at which PEEK parts change with temperature (which may be caused by the change) is very small.
PEEK seat ball valves are a popular choice for ball valves because they can effectively seal against leaks. However, not all PEEK valve seats are created equal.
Seatless PEEK valve seats do not have a seat; instead, they rely on a press fit between the valve’s body and the seat. Detachable PEEK valve seats have a removable seat that allows easy cleaning and replacement. Screw-on PEEK valve seats have a threaded insert that fits into a corresponding hole on the body of the ball valve.
Pipe valves are essential pieces of equipment used in industrial and commercial settings. One type of valve, the peek seat ball, controls fluid flow through a pipe. The basic operation of a peek-seat ball valve is simple. A small arm or cam on the valve seat rotates around a central pivot. This motion allows the operator to see around the edge of the seated ball. When the operator sees fluid flowing in one direction more than another, they can use this information to close the valve by moving the arm away from the seated ball.
