DescriptionHydraulically operated level control valve that manages reservoir filling and maintains predefined high and low levels via a non-modulating bi-level vertical float. Opens at a preset low level and provides drip-tight shutoff at a preset high level.
Features & Benefits- Designed for demanding conditions: excellent anti-cavitation behaviour; wide flow range; high stability and accuracy; drip-tight shutoff.
- Double-chamber actuator:
- Moderated valve reaction
- Protected diaphragm
- Optional operation at very low pressure
- Moderated closing curve for smooth operation
- Flexible, modular design for easy addition of options
- Obstacle-free flow path for unobstructed seat area
- Optional V-Port throttling plug for stable low-flow control
- High-quality materials suitable for potable and industrial water
- In-line serviceable for simplified maintenance
Design & Operation- Hydraulically controlled, non-modulating bi-level vertical float mechanism.
- Double-chamber valve body to ensure operational stability and diaphragm protection.
- Valve architecture reduces cavitation risks and delivers accurate level control across a wide flow range.
