-
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. It is also available in either T-pattern or Y-pattern configuration.
-
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
The body seat is an integral weld overlay and is part of the valve trim.
-
7. DISC
The disc is forged steel and is part of the valve trim. The disc seating surface is of the tapered or plugs type design. The disc is attached to the stem using a loose or swivel disc arrangement.
-
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.
