1.BODY

The body is forged steel and designed to the basic dimensional requirements of the applicable specifications such as API 602 and ASME B16.34. The body is available in both the full or conventional port design.
2.BONNET

The bonnet is forged steel, has an integral backseat and incorporates the stuffing box, which has dimensions per the applicable specifications such as API 602.
3.BODY-BONNET JOINT

Two different bonnet joint designs are available. These are either the bolted bonnet or the threaded and seal welded type.
4.GASKET

The bolted bonnet joint design valve uses a contained, controlled compression, spiral wound type gasket.
5.BONNET BOLTING

The bonnet bolting is manufactured of alloy steel in accordance with the requirements of the applicable specifications such as API 602 and ASME B16.34.
6.SEAT RINGS

The seat rings are steel and makeup part of the valve trim. They are pressed into the valve body and wedged into place, forming a seal with the body. The seating surfaces are ground and lapped.
7. WEDGE

The wedge, which is solid design, is forged or investment cast steel and is part of the valve trim. The seating surfaces are ground and lapped.
8. STEM

The stem is forged steel and part of the valve trim. It contains an integral back seat shoulder, which mates with the integral backseat of the bonnet. The stem is designed to the basic dimensional requirements of the applicable specifications such as API 602.
9. GLAND AND FLANGE

The gland, gland flange assembly utilizes a separate, two piece design. This self aligning design allows the flange to be unevenly tightened while the gland maintains its parallel alignment with the stem and stuffing box.
10. GLAND BOLTS AND NUTS

The steel/stainless steel gland bolt and nut assembly is a stud, double nut arrangement. This design allows complete removal from the valve when service is required. The use of industry standard thread full length studs and nuts also allows easy replacement should these items be lost or in need of replacement.
11. YOKE SLEEVE

The yoke sleeve is of forged stainless steel material having a high melting point and is resistant to wear and corrosion.
12. HANDWHEEL

The Hand Wheel is forged carbon steel of an open spoke design. This robust construction along with appropriate sizing allows for ease of operation.
