WATERVALVE 1/2 INCH; WATERVALVE 1/2 INCH0.5/1.

Description

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. Ammonia power elements and valves designed for saltwater 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.

Feature and Benefits

• Pressure balanced valve design Setpoint is independent from water inlet pressure
• High refrigerant pressure resistant bellows Refrigeration pressure may increase up to 28 bar without bellow damage
• Pressure actuated Direct and fast response to pressure variations
• 3/8, 1/2, 3/4" are angled body type valves with high Kv value Small dimensions with high flow capacity
• 3/8" up to 2" pressure valves "all range" types Reduces stock. One valve for all non-corrosive refrigerants
• Quick opening valve characteristics Fast response to pressure increase
• No close fitting or sliding parts in water passages No hysteresis increase or stuck valve caused by contamination
• Easy to disassemble. All parts can be replaced Valve can easily be repaired "in line". Valve piece parts are available "world-wide"
• Special bronze bodies and monel parts Used for sea water applications
• Power elements with stainless steel bellows available For use on ammonia filled equipment
• Wide range of pressure connection styles Possibility to meet the legislation in your country
• Nickel plated seats available for 3/8, 1/2, and 3/4" valves High resistant against erosion/ corrosion and cavitation
• Direct/reverse action Control action can be (factory) changed
