TWS VALVE, a trusted manufacturer of resilient seated butterfly valves, proudly introduces two advanced rubber seat solutions engineered for superior sealing and durability:
FlexiSeal™ Soft Rubber Seats
Crafted from premium EPDM or NBR compounds, our soft seats deliver exceptional elasticity and chemical resistance. Ideal for low-to-medium pressure applications, they ensure bubble-tight sealing across water treatment, chemical processing, and HVAC systems.
BackedSeal™ Reinforced Valve Seats
Featuring a patented backing structure, these EPDM/NBR hybrid seats combine flexible sealing surfaces with rigid support. The innovative design enables:
✓ 30% higher pressure tolerance vs standard seats
✓ Reduced deformation under cyclic stress
✓ Extended service life in oil & gas and industrial steam applications
Soft Rubber Seat:
The material is rubber, no backing. The soft rubber seat type, body with groove and matching this type seat.So, many people prefer soft rubber seat. The rubber seat covered on body, easy for installing, and apply for normal flanges. And soft rubber seat has lower torque.
Hard Rubber Seat:
The hard rubber seat is with phenolic resin backing.The hard rubber seat type, body no groove.Then, for hard rubber seat type, It is different from the soft rubber seat. it needs special flanges.
Some people still choose hard rubber seat. Because the price is lower and its stretch resistant. Reduce high torque and premature failure caused by rubber seat distortion.
For the hard rubber seat, when the valve size is below DN400, the backing material is phenolic resin. For bigger size from DN400, the backing material is aluminum.
