VALVES AND SEATS
Bonded and Replaceable
Full-Open Valve and Seat
Webbed Valve and Seats
The Full Open roughneck style valve's are designed for maximum flow characteristics. JCS full open drilling valves combine the strength of a forged alloy steel upper
body with precision casting to minimize flow restriction and fluid turbulence.
The forged, solid valve body construction, of this valve, with thick, rigid seat,
provides durability at high pressures.
The single piece, solid body construction of this valve provides the strength and
rigidity needed for high pressure drilling operations in the 5,000 to 7,500 psi
(34.5 to 51.7MPa) range
The snap on, polyurethane insert on standard replaceable. A non-replaceable
bonded insert upgrade is available. Various insert styles and materials are
available to suit any drilling condition.
Standard polyurethane inserts are good for 170° to 180°F (77° to 82°C) drilling
temperatures. The high temperature is specified for all drilling operations up to
and exceeding 300°F/7500psi, suitable for water or oil-based muds. Shelf life of
polyurethane insert is 5 years.
