United Gas Valves
The USI™ ball style gas meter valve in 3/4" through 2" are available with nickel/Chrome plating, a far more durable coating than other cationic electro-coating processes or painting. The 200 psig rated valve provides superior, maintenance-free performance at a price that is competitive with grease sealed plug valves. The USI valve is a full-port ball valve featuring a tamper resistant design with a triple-sealed, "blowout-proof" stem. Produced in accordance with all ASME B16.33 standards, the USI ball style meter valve will provide continuous maintenance-free service.
Dual Virgin EPDM O-Rings on Stem -- for maintenance-free sealing at normal and cold temperatures.
Full Diameter Round Port -- provides optimum flow and accepts any style valve changer.
Meets and Exceeds the requirements specified in ASME B16.33.
Maximum Pressure Rating -- 200 psig nominal working pressure. All valves are 100% tested -- 300 psig air and water test in the open and closed positions and 4 psig air and water test in the closed position.
Blow-out Proof Stem design is tamperproof. The stem is positively retained by the integral flange on the stem. The stem is made of brass to withstand high temperatures and resist corrosion and has an extra Virgin EPDM thrust washer providing a third sealing on the stem.
Integral Body Structure -- forged from C37700 solid brass bar stock.
Gas Compatibility dry natural or manufactured gas, air vacuum, butane, and propane.
Ball Type Closure Member -- made from brass plated with polished hard chrome over nickel to provide a positive, long lasting sealing surface. Resilient Teflon primary seals for maintenance-free sealing at normal and cold temperatures. Metal-to-Metal secondary fire seals.
Tamper Resistant Design -- makes the valve nearly impossible to disassemble.
C37700 Brass Locking Cap and Body – resists corrosion and is heat resistant.
