Soft Back Seat Proximity Switch Wafer Butterfly Valve

• 1. The soft-backed valve seat has a wider contact surface with the pipe flange, and the installation and sealing performance is better, without the need for a special flange for butterfly valves;
• 2. The soft-backed valve seat is highly replaceable and does not require any special tools. The replacement can be completed;
• 3. The wall thickness of the soft-backed valve body is larger than that of the hard-backed valve body, and the valve body is heavier.
• 4. The soft-backed butterfly valve has small torque.
• 5. A proximity switch butterfly valve offers enhanced control, monitoring, and automation capabilities in fluid management systems.
• 6. As the disc or lever of the Proximity switch butterfly valve moves, the proximity switch detects its position without making physical contact. Depending on the type of proximity sensor used (inductive, capacitive, or magnetic), it will sense the disc’s position relative to a set point.
