3in Fig 1502 Positive Choke – 10,000 psi Sour Service

Product Overview

The 3in Fig 1502 Positive Choke is designed for high-pressure flow control applications requiring dependable erosion resistance, controlled flow restriction, and long service life. Engineered for 10,000 psi sour service, this choke combines forged alloy steel construction with a compact integral body design to provide reliable performance in demanding oilfield environments.

The full-bore 3in configuration is ideal for high-volume flowback, well testing, production, and pressure control applications where fixed-orifice flow management is required.
