Asahi/America's new  ball valve is suitable for below-ground
service, and valves larger than 2" are available with an integrated gear
box. The SDR11 spigot ends are approved for maximum operating
pressures of 230 psi for water and 150 psi for air or gas.

Available in both metric pipe sizes and IPS pipe sizes, the ball
valve offers NBR seals for air or gas, and EPDM seals

for fluids. The ball valve can be easily installed using butt, socket or
electro-fusion technologies.
