One-piece forged, bonnet-less globe valve design reduces leakage points between body and bonnet and allows in-line maintenance without bonnet removal,

65° sloped and vertical globe valves have a lower pressure drop compared to vertical globe valves,

Non-rotating stem is hardened and ground and polished to ensure reduced torque and to prevent torsional damage to the packing,

Polished packing cavities and individually pre-pressurized combined graphite rings for a more positive seal, Tungsten-chrome-cobalt alloy flaps, seats and backseats ensure precise alignment of seats and flaps against high velocity flow, and maintain service life even in severe applications. Tungsten-chromium-cobalt alloy flaps, seats, and backseats provide long service life, even in severe applications.

Fully guided flaps ensure precise alignment of seats and flaps independent of side thrust from high-velocity fluids. This prevents scuffing of the valve body, scratching or bending of the stem, and extends the service life of the flap seal and valve body.

Seats are double-perforated to minimize the erosive effects of fluids draining through the main seat.

The backseat bevel is located on the stem, not on the flap, in accordance with API-600 and API-602.

The large clearance between the stem and flap allows for free movement of the flap.

Due to two pieces of flat steel below the flap, the flap is able to move freely inside of the stem. Nonrotating characteristic due to two flat steel plates on the underside of the flapper

Dynamic loads are optional, and dynamic loads maintain long-term tightness without maintenance. Bolt torque controls all spring loads,

Totally enclosed, lubricated stem drive system with two needle bearings ensures low operating torque,

Dust cover and sleeve protects stem from dirt, dust, and grit,

Position indicator is standard,

Excellent resistance to thermal variations,

Suitable for sewage and venting applications,

Selectable packing loads,

Flap types are available as occlusal, needle, or shutoff-check flaps. Optional,
