Modulating Valves

Positive Shut Modulating Diaphram Valve
Positive Shut Modulating Diaphragm Valve
This modulating valve is designed for applications where a tight shut-off is required due to filter tanks or surge chambers located below grade. The valve prevents an overflow or flooding of the filter room in case of pump shut-down while providing standard modulation of the main drain during operation. Valve configuration is normally closed and is activated by source water from the pool recirculating pump or auxiliary water supply.
