DN400 PN10 Gear OP EPDM Seat Two Shaft Lug Butterfly Valve
Basic Info of Lug EPDM Seat Two Shaft Lug Butterfly Valve
- Lug Butterfly Valve can be used for dead end service.
- Dovetail replaceable soft back seat lug butterfly valve refers to the fully lug wafer butterfly valve with the EPDM soft seat which can be replaced, it can reduce the cost when the seat is brocken.
- 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 butterfly valve has a lug design, which 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 butterfly valve adopts a centerline design, which makes the valve action more stable and accurate, reduces the opening and closing torque, and improves operating performance and ease of use.
- The precision-machined Stainless Steel 316 disc features a two-piece stem construction that enhances the valve’s flow capabilities and reduces turbulence.
