This straight cock design, Model 6390-LH for left-hand operation and Model 6390-RH for right-hand operation, can be field changed to operate in either position without the need for additional inventory or special parts. There is a 1-inch flange opening by 1-inch NPT. The valve is made of ductile iron and the handle is made of investment cast steel. Internal moving parts are made of stainless steel to resist corrosion. The ball is free-flowing on two Teflon seals, providing lubricity for ease of operation. The stem and ball are captured, preventing accidental blowout. O-ring seals ensure sealing of the stem.
