Frac Valves (Gate)
Full-bore slab or expanding gate valves that provide the primary isolation barrier in the stack, rated to 10K or 15K and built to API 6A for repeated cycling during pumping and flow-back.
Ball-Screw / Greaseless Frac Valves
Frac valves using a ball-screw actuation or sealed design to reduce or eliminate grease injection, lowering grease consumption and maintenance in abrasive proppant service.
Goatheads & Flowcrosses
Multi-outlet adapter blocks (goatheads) and flow tees/crosses that connect several lines of fracturing iron to a single bore, distributing high-pressure slurry into the stack.
Frac Adapters & Spools
Flanged adapters, crossover spools, and frac-iron adapters that mate the stack to the wellhead and to upper manifold connections across differing flange sizes and pressure ratings.
Flow-Back & Upper Manifolds
Manifold assemblies that route returns from the well to choke and separation equipment during well clean-up, combining valves, tees, and choke connections in a skidded arrangement.
Hydraulic Chokes
Adjustable or positive chokes used during flow-back to meter pressure and flow rate, controlling drawdown while managing proppant return and erosion.
Plug Catchers & Sand Knockouts
Vessels and screen assemblies that capture milled frac-plug debris and separate returned sand from the flow stream to protect downstream equipment.
Quick-Connect Wellhead Equipment
Clamp or dog-style connectors that allow rapid make-up and break-out of stack components between stages or wells, reducing rig-up time on zipper-frac operations.
