Valve Seats
We manufacture a wide range of soft seat configurations across many industries supplying major global customers.
Many ball and gate valves are rated by the pressure and temperature of service, commonly known as the valve class within the ANSI and ASTM classifications.
Polymer seats can achieve the sealing performance requirements throughout the range of classes from #150 thru #2500.
Typically the high modulus materials meet the requirement of the higher class valves.
Materials
-
PTFE
Filled grades provide wear resistance and can support seating loads of the higher class of valves.
For the categorisation of valve operating characteristics (in particular operating torque) plastic valve seat materials can be grouped in three categories Stiff, Normal and Flexible.
Our seals are manufactured to suit industry-standard grooves and assemblies, however, we also provide solutions in product and material specification.
In addition to usual testing for material specification, many applications can be replicated for tribological testing.
