Valve Balls & Seats
The use of a precision ball held against a valve seat is one of the most accurate
and cost effective ways to control the flow of liquid or gas. Machining Technologies
manufactures precision balls (our carbide balls)
and seats in a wide variety of sizes to provide the required performance.
Ball, Seat, and Match Lapping
We also manufacture valve balls in non-corrosive plastics. (our plastic
Machining Technologies specializes in the lapping techniques to generate high quality
ball-seating surfaces for valve and seats made of tungsten carbide and other hard
Vacuum Leak Testing
Machining Technologies uses a very sophisticated technique for leak testing by pulling
a high vacuum down stream of the seat and checking ball or poppet. The decay of
vacuum can quickly and accurately be measured to evaluate the quality of the seal
between the seat and the ball or poppet.
