2″ – 5000 PSI – BW API 6A DM Mud Gate Valve

2″ – 5000 PSI – BW API 6A DM Mud Gate Valve

Technical Datasheet

1. Product Overview

The DM Mud Gate Valve is a high-performance gate valve specifically designed for drilling mud systems in the oil and gas industry. It is designed, manufactured, and tested in strict accordance with API Spec 6A. The valve features a Rising Stem structure and Bi-directional Sealing. The gate is connected to the stem via a T-slot connection, allowing the gate to float within the slot and achieve pressure-energized sealing against the resilient seat inserts on both sides, ensuring bi-directional flow shut-off.

Applications: Drilling mud circulation systems, wellhead equipment, manifolds and flowlines, crude oil and sour gas pipelines, and drilling chemical handling.
