API V11 Ball and Seat
Matched carbide valve pairs for subsurface sucker rod oil well pumps
Product Detail
Product Category
API V11 Series Tungsten Carbide Ball and Seat Valve Pairs
Tungsten carbide ball and seat as valve pairs in the API V11 series for subsurface oil well sucker rod pumps supplied as finished valve pairs or as ball and seat blanks.
Problems It Solves
What Goes Wrong Today
- Sand cut on ball and seat faces destroys pump volumetric efficiency
- A leaking valve pair means pulling the rod string and losing production days
- Ball and seat bought separately do not always lap together correctly
Benefits
What Changes With Carbide
- Ball and seat supplied as a matched pair rather than as loose items
- Carbide faces resist the sand cut that ends the life of softer valve materials
- Blanks available for pump builders who lap and finish in house

FAQ
API V11 Valve Pairs FAQ
Which industries buy api v11 valve pairs from you?
Mainly Petroleum and Gas. Tell us your application and we will confirm what suits it.
Can you produce api v11 valve pairs to our drawing?
Yes. Custom made carbide parts to drawing are a normal part of our production. Send the drawing or a measured sample and we will confirm what is manufacturable in carbide.
What material are these parts made from?
Cemented tungsten carbide which is tungsten carbide grain in a cobalt binder. The grade direction is chosen with our engineers against your load case rather than sold as one universal grade.
How are the parts densified?
Blanks are densified by Sinter-HIP which applies isostatic gas pressure during the sintering cycle so residual porosity is reduced before machining.
What do you need in order to quote?
