SECTION III -SYSTEM COMPONENTS <br /> UL EX. 3470 ULC CEx747 Page 3-8 <br /> REV. 5 10-1-02 <br /> PULLEY TEE MECHANICAL GAS VALVES <br /> The Pulley Tee (Part No.427929) is used to change the direction The mechanical gas valves are designed to shut off the flow of gas <br /> of two wire ropes by 90°. It must be used in areas where the tem- to the appliances upon actuation of the regulated release assem- <br /> peratures are within the range of 32 °F to 130 °F (0 °C to 54 °C). bly.The valves are available in sizes of 3/4 in., 1 in., 1 1/4 in., 1 1/2 <br /> Pulley tees can be used in mechanical gas valve actuation lines in., and 2 in. Ansul style; and 2 1/2 in. and 3 in.Asco style.The <br /> and remote manual pull station lines. Pulley tees cannot be used valves are rated for natural and LP gas.Both styles are UL Listed. <br /> within a detection line.
