ZSPEC® oilfield ball valves are constructed of durable Ductile Iron, WCB or A105 forged bodies, depending on the size and pressure rating. All oilfield ball valves come standard with NACE trim and are tested and inspected per API 598. Threads conform to ASME B1.20.1 (NPT) and API 5B (LP) or (8RD).
Bolted Sleeve Couplings
ZSPEC® bolted sleeve couplings are ideal for use where quick and easy installation is needed. They are available for use on a wide range of pipe sizes. They can handle slight misalignment and will also reduce vibration. The shorter 5” and 7” lengths as well as the longer 12”, 16” and 24” lengths are available. 1” thru 16” diameter bolted sleeve couplings are in stock. Larger sizes can be fabricated upon request.
