Mud Line Gate Valves

Forum Mud Line Gate Valves are designed to the guidelines of API 6A with documentation and testing per API 6A, PSL1 and PSL2. They are designed for dependable service in high pressure pump and standpipe manifold systems. The seats are designed to provide a positive, tight shut off every closing cycle, even after long exposure to abrasion and scoring.

Twin metal wear inserts, encapsulated in an elastomer, form a cylindrically shaped plug made up of a gate slot and two flowports. Once closed, line pressure forces the gate up against the downstream port seals which are tested up to 7500 psi. Low pressure testing capability is available in both 5000 and 7500 psi configurations.

Forum is now offering Integral Union Mud Gate Valves. We have significantly reduced the need, time and cost associated with welding unions on weld end valves. A one-piece body is an inherently superior product than one with welded components that need to be stress relieved. Welded products increase the likely hood of potential failure and have inconsistent end to end dimensions. All Forum Mud Line Gate Valves are designed to the guidelines of API 6A with documentation and testing per API 6A, PSL 1 and PSL 2. Our valves are designed for dependable service in high-pressure pump and standpipe manifold systems, low pressure testing capability is also a feature on our 7500psi mud valves.
