Spring Return Butterfly Valves

A spring return butterfly valve is a type of butterfly valve with an actuator that uses pneumatic or hydraulic pressure to open the valve, while a spring automatically closes it when the pressure is released. This design provides a fail-safe feature by returning the valve to a default position, typically closed or open, in case of power or pressure loss. Spring return actuators offer simple and reliable operation, making them ideal for safety-critical applications. Spring return butterfly valves are commonly used in industries such as oil and gas, water treatment, and HVAC systems due to their ease of use, cost-effectiveness, and quick response.
