1 2-way pressure actuated water valves - ommercial applications These pressure actuated modulating valves control the quantity of water to a condenser by directly sensing pressure changes in a refrigerant circuit. The valves can be used in non-corrosive refrigerant systems. mmonia power elements and valves designed for salt-water applications are available. The valves have a quick opening characteristic and open on pressure increase (direct acting). Reverse acting (close on pressure increase) is possible. eatures ffpressure balanced valve design ffpressure actuated ff3/8, 1/2, 3/4 are angled body type valves with high Kv value ff3/8 up to 2 pressure valves all range types ffquick opening valve characteristics ffno close fitting or sliding parts in water passages ffasy to disassemble. ll parts can be replaced ffspecial bronze bodies and monel parts ffpower elements with stainless steel bellows available ffwide range of pressure connection s ffnickel plated seats available for 3/8, 1/2, and 3/4 valves ffirect/reverse action imensions in mm Valve size 3/ / / a (excl. valve depressor) 1: cm capillary 2: 7/16-20 UN flare nut 34 1: cm capillary 2: 1/4 tube for braze connection (incl. valve depressor mounted into machined flare) 1: cm capillary 2: 7/16-20 UN flare nut 3: copper sealring 15 1/4-18NPT (female) 5 7/16-20 UN
