Refer to LIT-125687 for All Series V47 Water pressure Actuated Water Valves . regulating Valves are designed The V47 Temperature Valves are for use only as operating widely used on heat exchangers devices. Where system to maintain optimum operating closure, improper flow or loss temperatures of internal of pressure due to valve combustion engines, air failure can result in personal compressors, hydraulic oil, etc.

3 Required. Valve design minimizes chatter and Water hammer. This product is made of copper alloy, which contains lead. The product is therefore not to be Specifications used on drinking Water . General Description 2018 Johnson Controls 1. Code No. LIT-125690. General Description A pressure-balanced design, employing synthetic rubber sealing diaphragms correctly proportioned to the valve port area, balances Valves against both gradual and sudden Water pressure changes, seals Water away from range spring and guides and provides protection against high Water surge pressures. Range spring and sliding parts are not submerged in Water where they would be subject to sedimentation and corrosion. Only five metal parts, made of corrosion. Only five metal parts, made of corrosion resistant material, come in contact with the Water -- valve disc holder, disc stud, valve seat, valve stem, and body. (See Fig 2.)

4 IMPORTANT: Before using this chart determine type of bulb needed in particular application. Table 1 -- Heating Bulb -- Bulb Temperature is always HIGHER than bellows Temperature . Table 2 -- Cross-ambient Bulb -- Bulb Temperature rises higher and drops lower than bellows Temperature . Recommended for general use with standard 75 to 135 F (24 to 57 C) range to maintain control at bulb location. Note: To provide satisfactory operation, always install valve with bellows down and spring cage up. Capillary end of Temperature Fig. 2 -- Typical cross- bulb should always be higher than plugged-end of bulb, or if sections of threaded type horizontal, the word TOP should be at the top or uppermost Valves . Interiors of flange surface of bulb. models are similar. Never subject Temperature bulb to temperatures in excess of 20F (11C ) above maximum range Temperature . Example: 75 to 135 F (24 to 57 C) range; maximum bulb Temperature not to exceed 155 F (68 C).
