3-Valve Manifolds, 3D, 3R, 3DH, and 3RH Series

Compactly designed, with three valves in one body

3D, 3R, 2DH & 3RH Series 3-Valve Manifolds are compactly designed, with three valves in one body, offering fewer potential leak points compared to traditional multi-valve configurations, suitable for liquid level and differential pressure applications. The valves feature a two-piece stem design, with the upper stem threads roll-hardened to isolate the lubricant from the system media, and the lower stem surface specially hardened. These manifolds support pressures up to 10,000 psig (690 bar) and temperatures from -65°F to 1,200°F (-54°C to 649°C). The non-rotating lower stem moves vertically instead of via threaded lifting, reducing packing wear per stroke and minimizing wear between the seat and valve head. The valves provide back-sealing functionality in the fully open position, with a handle secured by a locking screw for durability. All manifolds are factory-tested at rated working pressures.
