4" 2,000 PSI Fig 206 MxF Ball Valve – Low-Pressure Hammer Union Isolation Valve

The 4" Figure 206 Male x Female (MxF) Ball Valve is a robust, quarter-turn isolation solution designed for reliable flow control in low-to-medium pressure fluid handling systems. Rated for a Cold Working Pressure (CWP) of 2,000 PSI, this valve is engineered for high-volume transfer lines where rapid connection and positive shut-off are critical. It is an essential component for water, oil, gas, and drilling mud applications where the ease of hammer union integration is required.

This valve features integrated 4" Figure 206 hammer union ends—a Male sub on one side and a Female threaded hub with a wing nut on the other. This configuration allows for "MxF" (Male x Female) inline installation, enabling the valve to be quickly "hammered up" into existing flowlines without the need for additional adapters or flanges. The full-port internal design ensures minimal pressure drop and maximum flow efficiency, making it ideal for high-rate transfer operations.

Manufactured from high-grade forged steel, the Fig 206 ball valve is built to withstand the rigors of field use. The precision-ground stainless steel ball and reinforced seats provide a bubble-tight seal and smooth operation, ensuring long-term reliability in suction lines, discharge manifolds, and general utility service.

Features & Benefits

• 2,000 PSI CWP Rating: Optimally designed for safe and efficient operation in low-to-medium pressure transfer and utility applications.

• Integrated Fig 206 Ends: Features industry-standard 4" Figure 206 Male x Female hammer unions for fast, secure, and leak-proof connections in the field.

• Full Port Design: Maximizes throughput and minimizes turbulence and pressure loss, essential for high-volume fluid transfer.

• Quarter-Turn Operation: Provides rapid manual shut-off and clear visual indication of valve position (open vs. closed).

• Durable Forged Steel Body: Engineered for high impact resistance and structural integrity in demanding oilfield and industrial environments.

• MxF Configuration: Streamlines manifold assembly by allowing direct connection between male and female components without intermediate piping.

Specifications & Technical Details

Applications

The 4" Fig 206 MxF Ball Valve is widely used in fluid transfer systems that require frequent assembly and disassembly. Typical applications include installation on water transfer lines, drilling mud suction and discharge manifolds, portable tank batteries, and low-pressure utility headers. Its rugged design makes it a staple for frac water heating units and general oilfield fluid management.

Quality Assurance

Every valve undergoes rigorous quality control and testing procedures to ensure field readiness. This includes dimensional verification of the hammer union interfaces and high-pressure hydrostatic testing of both the body and the seats to guarantee a bubble-tight seal at the rated pressure. Full material traceability is maintained to ensure the highest standards of safety and performance.
