API 6A Check Valves – Engineered for reliable backflow prevention in harsh oil & gas environments, featuring 15,000 PSI pressure rating and NACE MR0175-compliant materials for sour service. Our dual-plate/swing check valves reduce water hammer risk with non-slam design, while tungsten carbide-coated seats ensure 5x longer service life in abrasive flows. Available in 2" to 24" sizes with PSL1-PSL3G certification, ideal for pipeline, wellhead, and offshore applications.
Product Details

High-Temperature Expansion Valves for Extreme Service Conditions
(API 6A/PSL3G Certified | 15K PSI Rated | Carbide-Sprayed Seals)


Product Overview

Our high-temperature expansion valves (2-1/16" to 7-1/16") are engineered for thermal expansion control in oil & gas, power plants, and chemical processing systems. Featuring metal-to-metal carbide-sprayed seals, these valves withstand abrasive/corrosive media while maintaining leak-proof performance from -75°F to 350°F.


Key Features & Benefits

1. Robust Construction for Harsh Environments

  • Pressure Range2,000–15,000 PSI with K-X temperature rating (API 6A compliant).
  • Wear ResistanceCemented carbide-sprayed valve plates/seats extend service life by 3x in erosive flows.
  • Material GradesAA-FF alloys (optional NACE MR0175 grades for sour gas).

2. Precision Thermal Management

  • Metal Seal Design: Zero-leak performance during thermal cycling and high-ΔP conditions.
  • Low-Torque Operation: Optimized for rapid response in emergency shutdown scenarios.

3. Compliance & Customization

  • CertificationsAPI 6A PSL1-PSL3GPR1/PR2 Performance Level.
  • Actuator Options: Manual, pneumatic, or hydraulic actuators for automated control.
