API 6A High-Pressure Slab Gate Valves (Manual, Hydraulic & Electric Actuated)

  • Severe fluid erosion, high differential pressure, and sand accumulation frequently lead to seat leakage and stem packing failures in wellhead valve manifolds.
  • Built to API Spec 6A and NACE MR0175, our slab gate valves feature bi-directional metal-to-metal sealing, non-rising stems, and optional hydraulic/pneumatic fail-safe actuators.
  • Ideal for Christmas trees, choke & kill manifolds, high-rate hydraulic fracturing, and fast-track MRO gate/seat repair kit replacements.

Main Advantage & Solution

  • Gate & seat washouts caused by high-velocity proppants and sand during frac and flowback.
    Solution: Hardfaced slab gates and floating seats with Stellite or Tungsten Carbide cladding provide zero-leakage metal-to-metal isolation up to 25,000 Psi.
  • Need for immediate ESD (Emergency Shut-Down) protection in unmanned or high-risk wells.
    Solution: Surface Safety Valves (SSV) feature fail-safe spring-return hydraulic/pneumatic actuators for rapid automatic valve closure upon signal loss or line pressure anomalies
  • Excessive downtime during field maintenance and trim overhauls.
    Solution: Fully interchangeable trim components (gates, seats, stems, and seal kits) designed to standard Cameron FC/FL dimensional profiles for fast online servicing.

Application Scenarios

  • Wellhead & Christmas Trees: Primary isolation valves for production and master valve blocks.
  • Hydraulic Fracturing Trees: High-bore, sand-resistant frac valves handling high proppant volume pumping.
  • Emergency Shut-Down (ESD) Systems: Automated SSVs installed on surface flowlines for safety compliance.
  • MRO Spare Parts Replacement: OEM-compatible replacement gates, seat rings, stem packings, and bonnet gaskets.
