Open the catalog to page 5Control Applications Remote Control & Check Valves A 3-way solenoid valve, activated by an electric current or an electric pulse, opens or closes the main valve. The standard valve is “normally close”. The “normally open” is optional. Electric activation can be added to other control applications on request. EL - Solenoid Controlled Valve The valve is in the “open” position when the upstream pressure is higher than the downstream pressure. Should the upstream pressure drop below the downstream pressure, the valve will instantly close, preventing return flow. Opening and closing speeds are...
Open the catalog to page 6Control Applications PS - Pressure Sustaining Valve PS(R) - Pressure Relief Valve The valve maintains upstream pressure, regardless of flow rate variations. The valve will be in the “closed” position if the upstream pressure drops below the set-point and will be “fully-opened” when the upstream pressure exceeds the set-point. Pressure Sustaining & Relief Valves DI - Pressure Differential Sustaining Valve QR - Quick-Relief Safety Valve The valve opens instantly when the pressure in the pipeline exceeds the safe level, thus relieving excessive pressure from the network. When the pressure...
Open the catalog to page 7Control Applications Level Control Valves The main valve is controlled by a float valve, located in the tank or reservoir and set at the required maximum water level. The valve maintains the maximum level continuously. Optional Addition: Surge-Preventing Closure (SA). FL - Modulating Float Controlled Valve A Float valve (model 70-550) controls the main valve, closing it when the water reaches maximum level, and opening it when the water drops to its preset minimum level. The differential between the maximum and the minimum levels is adjustable, at a wide range. Optional Addition:...
