Manual override valve with positive-locking mechanism, featuring tactile position feedback through a stainless steel detent system. The chrome-plated lever offers 180° rotation with clear position indicators. Designed for systems requiring fail-safe manual control without electrical components. Includes built-in silencer for exhaust air noise reduction (75 dB(A) max).
- Emergency override in automated production lines
- Pneumatic tool control stations
- Material handling equipment safety stops
- Training/test bench setups for fluid power systems
- Mobile hydraulic/pneumatic hybrid systems
Maintenance protocol:
Lubricate pivot points every 5,000 cycles using ISO VG32 hydraulic oil.
Avoid side-loading the actuator lever - maximum permissible lateral force 5N.
Critical note:
Not compatible with phosphate ester-based fluids. Always install downstream
filter (25μm or finer) when using in particle-sensitive applications.
