FLOW SELECTOR

Used in diverter vent lines, flow selectors always keep the discharge line open and permit selection of a downwind line. They cannot be shut in.
FS™

For floating drilling and platform rig service, with integral venting. Diverter loads through a 49-1/2" or 60-1/2" rotary table. Diverter closes on an open hole with no insert packer required.
FSP™

Diverter/BOP systems for bottom-supported offshore rigs incorporate integral venting. With no insert packer required, the diverter closes on an open hole or to handle tool and pressure tests.
GAS HANDLER™

For deepwater, floating drilling, the GH Diverter uses annular closing devices to handle gas bubbles that expand as they ascend through a long riser. Mounted below the telescopic joint, it permits pressure control in the annulus.
MSP™ 21"- 2000 PSI

Applicable to surface installations, this lightweight, compact MSP provides both diverter and annular BOP functionality.
MSP™ 29" - 500 PSI, 30" - 1000 PSI

Well suited for surface operations, this MSP has withstood the test of time, proving itself as both a diverter and an annular BOP.
RISER FILL-UP VALVE

For unplanned events such as an emergency disconnect of the LMRP, a gas kick that evacuates the riser or a failure of the lower riser section, the Hydril Pressure Control riser fill-up valve is an absolute necessity.
SEAL-ALL™ DIVERTER INSERT

Ensures safety on floating drilling rigs during completion and workover operations, when combinations of drill pipe and auxiliary lines in the well bore increase the difficulty of diverting gas that otherwise could reach the drill floor.
