Valves are the lifeline of oil and gas operations, controlling flow and pressure in environments where precision and safety are critical. Discover how Barksdale’s Shear-Seal® technology delivers unmatched reliability, leak-free performance, and durability for upstream, midstream, and downstream applications.

Why Valves Matter in Oil & Gas

Valves are the unsung heroes of oil and gas operations. They regulate flow, maintain pressure, and ensure safety in environments where failure is not an option. From drilling rigs to refineries, valves must withstand extreme pressures, corrosive fluids, and unpredictable conditions. That’s why Barksdale’s Shear-Seal® technology has become the benchmark for reliability and performance.

What Makes Shear-Seal® Technology Different?

Unlike conventional valve designs, Shear-Seal® valves use fluid pressure to maintain a superior metal-to-metal seal that improves with use. This unique design delivers:

• Virtually Leak-Free Performance: Reduces environmental risk and operational downtime.

• Self-Lapping Action: Prevents contamination, ensuring consistent control over time.

• Extended Lifespan: Hardened sealing surfaces and robust construction for long-term durability.

Product Lineup for Critical Applications

Barksdale offers a complete range of valves tailored for oil and gas applications:

1. Heavy-Duty Valves for BOP Control Units

• Pressure ratings up to 15,000 psi (1034 bar)
• Corrosion-resistant materials for offshore and onshore environments
• Rack-and-pinion pilot actuators for reliable shifting
• Available in 2- and 3-position configurations with position indication

2. High-Pressure Valve Series 4140

Applications Across the Oil & Gas Value Chain

• Upstream (Drilling & Exploration):
  Shear-Seal® valves are critical in Blowout Preventer (BOP) control systems, ensuring rapid response and fail-safe operation during drilling.

• Midstream (Transportation & Storage):
  Valves maintain pressure integrity in pipelines and storage facilities, preventing leaks and ensuring safe transport of hydrocarbons.

• Downstream (Refining & Production):
  In refineries, valves regulate flow in high-temperature, high-pressure environments, supporting continuous and efficient production.

Why Choose Barksdale Valves?

• Safety First: Leak-free performance minimizes environmental hazards.

• Reliability Under Pressure: Proven track record in the harshest conditions.

• Versatility: Multiple port sizes (¼” to 1½” NPT) and SAE options for easy integration.

• Compliance: Meets industry standards for hazardous environments.
