MAIN COMPONENT & PARTS

1. BODY:
Strong and Robust in ASTM forged steel material.
Designed to the requirements of API 602 and ASME
B16.34. Available in Standard and Full Bore design.

2. SEAT:
Part of the valve trim to API 602, the body seat is a separate seat ring pressed and seal welded into the valve body. this eliminates potential leak paths.

3. WEDGE:
Part of the valve trim to API 602, the wedge is in ASTM forged steel material. Solid wedge as standard.

4. STEM:
Part of the valve trim to API 602, the stem is in ASTM forged steel material and designed to the basic dimensional requirements of aPI 602. Comes with an integral backseat shoulder that seals with the integral backseat of the bonnet.

5. GASKET:
Spiral Wound Type body gasket as standard.

6. BONNET:
Strong and Robust in ASTM forged steel material. Designed to the requirements of API 602 and
ASME B16.34. Comes with an integral backseat and stuffing box.

7. GLAND PACKING:
Graphite packing as standard. Other materials available upon request.

8. GLAND:
Alloy steel material to ASTM standards.

9. GLAND FLANGE:
The gland and gland flange is designed as a separate two piece assembly. This self aligning feature allows the gland flange to be tightened unevenly while the gland maintains its parallel alignment with the stem and stuffing box.

10. GLAND BOLT/NUT:
Stainless Steel Material to ASTM standards. The gland bolt/nut assembly is a stud, double nut arrangement. This allows complete removal during servicing of the valve.

11. BONNET BOLT:
Alloy steel material to ASTM standards.

12. HANDWHEEL:
Durable and Robust design. Ease of operation with the appropriate sizing.

13. NAMEPLATE:
Allows full traceability.
