Excellent sealing and chemical resistance: EPDM valve seat has high elasticity and resilience, so it can effectively seal the valve and prevent leakage and leakage. besides，It has excellent chemical stability, can resist corrosion and erosion from a variety of chemicals, and is suitable for various media.
Temperature adaptability: EPDM valve seats can work normally in a wide temperature range, with good heat resistance and cold resistance from minus 20 to 80 degrees Celsius.
Lug design: Lug style butterfly valve has a lug design. This can reduce the erosion of the valve seat and sealing ring by the medium, and improve the service life and reliability.
Centerline design: This lug style butterfly valve adopts a centerline design. It makes the valve action more stable and accurate, reduces the opening and closing torque, and improves operating performance and ease of use.
hard back seat : the material of the lug style butterfly valve is composed of rubber on the outside wrapped on the hard back inside. The installation method is using a professional valve assembly platform to press the valve seat into the valve body through a machine.
