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. For very low-pressure applications, refer to the Full Powered Opening and Closing Model 710-B.
The Model 710 is a solenoid controlled valve equipped with a 3-Way solenoid pilot. The normally open solenoid  applies pressure to the upper control chamber , harnessing valve differential pressure to power the diaphragm actuator, closing the main valve. Energizing the solenoid vents control chamber pressure, causing the main valve to open fully. The lower control chamber  is open to the atmosphere. In cases where pipeline water is contaminated (corrosive, debris laden) external control fluid is often used. For 10” and larger valves, an accelerator  quickens valve response.
The Solenoid Controlled Valve shall either open fully or shut off in response to electric signals.
Main Valve: The main valve shall be a center guided, diaphragm actuated globe valve of either oblique (Y) or angle pattern design. The body shall have a replaceable, raised, stainless steel seat ring. The valve shall have an unobstructed flow path, with no stem guides, bearings, or supporting ribs. The body and cover shall be ductile iron. All external bolts, nuts, and studs shall be Duplex® coated. All valve components shall be accessible and serviceable without removing the valve from the pipeline.
Actuator: The actuator assembly shall be double chambered with an inherent separating partition between the lower surface of the diaphragm and the main valve. The actuator assembly shall not consist of any closing spring nor spring-like device. The entire actuator assembly (seal disk to top cover) shall be removable from the valve as an integral unit. The stainless steel valve shaft shall be center guided by a bearing in the separating partition. The replaceable radial seal disk shall include a resilient seal and shall be capable of accepting a V-Port Throttling Plug by bolting.
Control System: The control system shall consist of a 3-Way solenoid pilot valve (for 10” and larger valves, an accelerator shall be added to the solenoid), an isolating cock valve, and a filter. The assembled valve shall be hydraulically tested.
Quality Assurance: The valve manufacturer shall be certified according to the ISO 9001 Quality Assurance Standard. The main valve shall be certified as a complete drinking water valve according to NSF, WRAS, and other recognized standards.
In complex distribution networks, management optimization of sources and consumers is essential:
The Model 710 is well suited to meet all the above needs and more. It should be included for placement in multiple locations during the design stage or with changing needs.
In a filter battery installed as part of a water treatment system, each filter requires periodic back flushing. This process entails reversing the direction of flow through each filter. Two Model 710 valves [V1] & [V3], installed upstream from each filter, enable this reversal. The "untreated water valve" [V1] is Normally Open and the "back flushing inlet valve" [V3] is Normally Closed.
