MASCOT GFlo Globe Control Valve

The GFlo Globe Control Valve

Superior performance in liquids and gaseous services is the hallmark of the GFlo Globe Control Valve by Zeco. Easy, quick, and economical maintenance makes the GFlo Globe Control Valve more user-friendly. The spring cylinder actuated GFlo imparts stiffness and maintains very high precision in positioning. A strong response, repeatability, and high-speed controlled movement are the characteristics absent in diaphragm-operated control valves. GFlo has the thrust capability to shut off against higher fluid pressures, up to 150 Psi / 10.30 Bar air supply.

Valve closure is dependent on springs in most diaphragm actuators. The unique design of GFlo enables it to combine the spring force, fluid pressure, and supply air pressure to achieve a tight shutoff. A self-aligning seat ring adds to and further improves the shutoff capability.

Galling at the cage is the culprit in many common maintenance issues with globe valves because of the close metal-to-metal contact between plug & cage. The GFlo has two top heavy-duty stem guides. Interference between the plug and seat retainer does not exist in GFlo. Easy and quick maintenance is due to the clamped-in seat and top entry trim.
