Pressures as High as 740 psi
For Clean and Abrasive Services

LIVE LOADED PACKING SYSYTEM

Blow-Out proof stem design to ensure workman safety
Tight tolerance between the stem and the stem thrust washer allow for precise stem to ball contact.
Live-Loaded stem packing to compensate for temperature fluctuations and normal wear.
Care is taken not to over torque the stem packing at the testing facility. This provides the customer with the longest packing life possible. At the same time, it keeps the valve torque at a minimum.
Stem system certified to ISO 15848 available on request.

FEATURES

The body and end connections are bolted with a metal to metal contact to ensure that proper compression on the body gasket is achieved. This metal to metal contact also guarantees that the dimensions inside the valve are correct. The torque is constant, and both the body and seat seal gaskets will always have the proper compression.

SEAT STYLES

P Seat - Spring Loaded (Standard)

For unidirectional applications. The sealing seat is available as a separate seat ring for reparability, or integral with the tailpiece for high temperature applications. The spring seat OD seal prevents media from building up between the spring and the back of the seat.

View Details

Temperature Range: -40 to 1000 deg F
Application: Steam, Hot Air, Gases, Low Pressure Differentials, High Temperatures
Shut-Off: Class V, Class VI, Bubble Tight

O Seal - Graphite Sealed Seat

A double seal design providing both spring loading and excellent sealing capabilities. There is no area for media to build up behind the seat, which prevents the valve from locking up.

View Details

Temperature Range: --40 to 650 deg F
Application: Steam, Abrasion, Low Pressure Differentials, Fine Solids, Emulsions
Shut-Off: Class V, Class VI, Bubble Tight

G Seal - Graphite Sealed Seat

A series of Graphite seal rings behind the metal seat prevents media from building up behind the seat. The rings also allow for expansion of the internal valve components in high temperature applications. This design is great for applications involving fine solids as the graphite prevents the media from building up behind the seats.

View Details

Temperature Range: -20 to 1500 deg F
Application: Steam, Abrasion, High Temperatures, Fine Solids, Slurry
Shut-Off: Class V, Class VI, Bubble Tight

T Seat - Reinforced TFE Seat

The T Seat Style designates a soft seat material. There are many seat materials available with TFM being the standard option. A metal lip on the body and tailpiece provides fire safety and meets API 607 requirements.

View Details

Temperature Range: -20 to 450 deg F
Application: Steam, Low Pressure Differentials, Emulsions, Nonabrasive Media
Shut-Off: Class VI, Bubble Tight
