700 SERIES HYDRAULICALLY OPERATED VALVES
Level Control Valves
Model 750-66-B Level Control Valve with Bi-Level Vertical Float
The Model 750-66-B Level Control Valve with Bi-Level Vertical Float is a hydraulically-controlled, diaphragm actuated, double-chambered control valve. The valve is hydraulically powered to fully open at pre-set reservoir low-level, and to shut-off at pre-set high level regardless of valve differential pressure.
Model 750-67 Level Control Valve with Modulating Vertical Float
The Model 750-67 Level Control Valve with Modulating Vertical Float is a hydraulically-controlled, diaphragm actuated, control valve that controls reservoir filling to maintain constant water level, regardless of fluctuating demand.
Model 750-60 Level Control Valve with Modulating Horizontal Float
The Model 750-60 Level Control Valve with Modulating Horizontal Float is a hydraulically-controlled, diaphragm actuated, control valve that controls reservoir filling to maintain constant water level, regardless of fluctuating demand.
Model 750-65 Level Control Valve with Bi-Level Electric Float
The Model 750-65 Level Control Valve with Bi-Level Electric Float is a hydraulically-operated, diaphragm actuated, control valve that controls reservoir filling in response to an electric float switch signal, opening at pre-set low-level and shutting-off at pre-set high level.
Model 753-66 Level Control and Pressure-Sustaining Valve with Bi-Level Vertical Float
The Model 753-66 Level Control and Pressure-Sustaining Valve with Bi-Level Vertical Float is a hydraulically-operated, diaphragm-actuated, control valve that controls reservoir filling, opening at pre-set reservoir low-level and shutting-off at pre-set high level.
Surge Valves
Model 735 Surge-Anticipating Control Valve
The Model 735-M Surge-Anticipating Valve is an off-line, hydraulically-operated, diaphragm-actuated valve. The valve, sensing line pressure, opens in response to the pressure drop associated with abrupt pump stoppage. The pre-opened valve dissipates the returning high pressure wave, eliminating the surge. The Model 735-M smoothly closes drip-tight as quickly as the relief feature allows, while preventing closing surge.
The valve also relieves excessive system pressure.
Model 735-55 Surge-Anticipating Control Valve with Solenoid Control
The Model 735-55-M Surge-Anticipating Valve with Solenoid Control is an off-line, hydraulically-operated, diaphragm actuated valve. The valve immediately opens in direct response to any power failure even prior to the pressure drop associated with abrupt pump stoppage. The pre-opened valve dissipates the returning high pressure wave, eliminating the surge.
The Model 735-55-M, sensing line pressure, smoothly closes drip-tight as quickly as the relief feature allows, while preventing closing surge. The valve also relieves excessive system pressure.
Solenoid Valves
Model 710 Solenoid-Controlled Valve
The Model 710 Solenoid-Controlled Valve is a hydraulically-operated, diaphragm-actuated, control valve that either opens fully or shuts-off in response to electric signals.
Model 710-20 Solenoid-Controlled Valve with Check Feature
The Model 710-20 Solenoid-Controlled Valve with Check Feature is a hydraulically-operated, diaphragm actuated, control valve that either opens fully or shuts off in response to electric signals. The check feature prevents reverse flow through the valve.
Model 710-B Powered-Opening Solenoid-Controlled Valve
The Model 710-B Powered-Opening Solenoid-Controlled Valve is a double-chambered, hydraulically operated, diaphragm-actuated, control valve that either opens fully, regardless of valve differential pressure, or shuts-off in response to electric signals.
Electronic-Control Valve
The Model 718-03 Electronic-Control Valve combines the advantages of an excellent modulating, line-pressure driven, hydraulic control valve with the advantages of electronic control. This valve responds to signals from the electronic controller BERMAD BE (optional) according to the set values programmed into the controller.
Features include:
- Pressure control
- Flow control
- Leakage control
- Level control
- Temperature control
- Mixture control at mixing junction
Burst Control Valve
Features include:
- Zonal shut-off at burst
- ``Older`` burst-susceptible networks
- Outlets from reservoir at earthquake risk
- Vulnerable network infrastructure facilities
- Networks liable to mechanical damage
The Model 790-M Burst Control Valve is a hydraulically operated, diaphragm-actuated, control valve that upon sensing flow in excess of setting shuts-off and locks drip-tight, until it is manually reset. As long as flow is lower than the setting, the valve remains fully open, minimizing head-loss.
