ISO 5211 Spring Return VALVE Handles

Spring Return Handles for ISO-5211 Valves



Spring return handles for ISO 5211 mounting flange for ECON ball valves (Fire-Safe) protect personal life and the environment from unnecessary sample waste.


The Mechatest design ISO-5211 spring return handles also known as “deadmans” handles are designed for ISO 5211 ball valves from ECON, the function in this case is always that the valve is (spring) return to closed position when the handle will be released.

For this purpose Mechatest designed a spring return handle for ECON ball valves with ISO-5211 mounting flange, the 90° rotation is for 2-way ball-valves. 

 

Designed for standard or Fire-Safe ECON or other ball valves with mounting flange according to ISO 5211, normally suitable for direct mounting of a (pneumatic or electric) drive or this spring return handle.




  • Failsafe operation
  • For ISO 5211 mounting flange type 2-way ball-valves series ECON fig. 7442 (BSP thread), fig. 7442FS (fire safe BSP thread), fig. 7444 (BSP thread), fig. 7542 (NPT thread), fig. 7542FS (fire-safe NPT thread), fig. 7544 (NPT thread), fig. 7383 (wafer flange), fig. 7383FS (fire-safe wafer flange).
  • The 2-way function spring return handles can be mounted as spring-to-close or spring-to-open.
  • Panel mount facility.
  • Zero maintenance.
  • Completely Stainless Steel.

It often happens that manual operated instrumentation ball-valves are not turned in the required position after operation. Most times this means that the valve is not closed. It can be very important (for safety reasons) that the ball-valve automatically rotates back. This can be achieved by mounting a spring return adapter on top of a manually operated ball-valve. This is particularly required for sampling valves. Spring return handles protect personnel and environment from unnecessary sample waste. The spring return handles also known as “dead mans” handles, the function in this case is always that the valve is spring)return to closed position when the handle will be released. The Mechatest spring return handle can directly mounted to several types Swagelok, Fitok and Hoke instrumentation ball-valves.

  • The spring return handles also known as “deadmans” handles, the function in this case is always that the valve is (spring) return to closed position when the handle will be released.
  • Effectively dealing with the effluent and waste from sample taps is a concern to both environmental and safety engineers at petrochemical plants. The Mechatest spring return handle guarantee failsafe operation for small instrumentation ball valves. The spring return handle with ball-valve is the perfect solution for the most common lab sample points.
