This system consists of a surface safety gate valve,
high pressure pilot, low pressure pilot, and a velocity
check valve. The LPO SSV’s use line pressure as a
control pressure to activate the actuator, resulting in
a self-operating system. High and low pressure pilots
sense line pressure continuously. Any abnormal
pressure changes such as high pressure increase or
low pressure decrease cause these pilots to exhaust
control pressure from the safety valve, closing the
valve. Installed as a secondary master on the tree, on
flow lines, header valves, gathering lines, pipelines,
and transmission lines, the WOM LPO SSV is ideal
for single point protection.

The Magnum gate valves provide sealing reliability that is unmatched in the
industry. The patented design has been proven in hundreds of well control
applications during drilling, testing, and production...onshore, offshore, and
subsea.

Key to the Magnum’s superior bi-directional sealing is the “Sure-Seal” system.

This unique “thru- conduit” design provides both upstream and downstream
sealing, creating a pressure energized balance between the slab gate and
seat assemblies. The “Sure-Seal” seats expand against the floating gate when
subjected to line pressure to form a positive metal-to-metal seal.

The body cavity is exposed to line pressure only during valve opening and
closing, ensuring better lubricant retention, less exposure to line contaminants,
and longer service life with less maintenance.
