Diaphragm valve IR-735-55-M

hydraulically-operatedpressure-controlfor battery

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. PRODUCT FEATURES & BENEFITS Replaces surge air vessels Relieves surge, fail-safe open Minimal maintenance Economy of space Lower investment and maintenance costs Especially economic for higher pressure ratings Solenoid controlled Low cost wiring Wide range of pressures Line pressure driven No motor required Adjustable hydraulic actuation Double chamber Moderated valve closing (no surges) Protected diaphragm In-line serviceable – Easy maintenance Obstacle free, full bore – Uncompromising reliability Balanced seal disk – High flow capacity TYPICAL PRODUCT APPLICATIONS Typical Applications In this system, a pump battery supplies the main line through a manifold. The Model 735-55-M: Eliminates surge upon power failure Provides surge free switching between “on-duty” pumps. Closes smoothly according to pilot setting The solenoid control is especially advantageous when:
