Previous generation gate valves were gear driven and as a result, were slow to operate in either direction and difficult to open under high-differential pressure. This slow open/close speed meant gates were easily worn or damaged by abrasive flow, rendering valves useless or creating operational hazards.
Engineered by AWC, Torque Master and Hydro Master valves represent the latest generation of ball-screw valve technology. The Torque Master valve is manually operated while the Hydro Master valve includes a reliable hydraulic actuator that provides numerous safety, efficiency and operational benefits for hydraulic fracturing.
All valves can be ordered with stainless steel inlay in the RTJ, seat pockets and bonnet-seal ring grooves. Additionally, all valves feature standard gates instead of reverse acting gates - allowing field personnel to easily see if the valve is open or closed - and include a manual-locking screw.
The technology used in Torque Master and Hydro Master valves enables them to open or close more quickly and requires significantly fewer rotations to complete the cycle, allowing the valves to be operated in either direction in a fraction of the time. This fast operating speed reduces the wear hazard on sealing surfaces in the presence of abrasive flow and improves the efficiency and effectiveness of fracture operations.
Also, because the new ball-screw valves require up to 75 percent less torque to operate, they can be opened very easily, even in the presence of high-differential pressure.
In terms of mechanical integrity, the Torque Master and Hydro Master valves offer unmatched security for hydraulic fracturing and other oilfield operations. Exclusive emergency upper and lower back-up stem packing assemblies provide even more security to these operations. The gates and seats are interchangeable between the two valves making repair easier and more cost effective.
Sharing the same valve body design as the Hydro Master, the Torque Master is a manually operated valve that offers unmatched security and mechanical integrity. The new ball-screw valves require less torque to operate ensuring the valves can be opened or closed very easily even in the presence of high-differential pressure.
H2S ready The Torque Master gate valve is H2S service ready. There is no need to special order.
Field proven Over 7,500 frac valves in service during the last 10 years.
Assured safety Exclusive emergency upper and lower back-up stem packing assemblies.
Low-torque operation 50-75 percent lower than conventional ACME mechanical screw stems.
Stainless steel inlays Torque Master valves can be ordered with S/ST inlay in RTJ, seat pockets and the bonnet-seal ring grooves. Valves also incorporate S/ST upper and lower stems.
Longer gate and seat life Fast-opening time of the Torque Master valve and lower transit time mean longer life for internal parts.
Wide-operating range Low-pressure/flow operations enhanced by the exclusive cushion-seal assemblies incorporated into the hard-faced, single-piece seats.
Hydraulically operated, the Hydro Master offers numerous benefits in terms of safety, efficiency and operability for hydraulic fracturing operations.
Clear valve status Hydro Master gate valves feature standard gates instead of reverse acting gates, allowing field personnel to easily see if the valve is open or closed.
Secure operation Hydro Master gate valves include a manual-locking screw.
Field proven Over 4,000 frac valves in service during the last 10 years.
Assured safety Exclusive emergency upper and lower back-up, stem-packing assemblies.
Low-torque operation 50 -75 percent lower than conventional ACME mechanical screw stems.
Stainless steel inlays Can be ordered with S/ST inlay in RT, seat pockets and the bonnet-seal ring grooves. Valves also incorporate S/ST upper and lower stems.
