Zhejiang Gute Forged Steel Valves Design

1. ZHEJIANG GUTE. The GUTE is forged steel, has an integral backseat and incorporates the stuffing box, which has dimensions per the applicable specifications such as API 602.
2. ZHEJIANG GUTE. Two different GUTE joint designs are available. These are either the bolted  GUTE or the threaded and seal welded type.
3. GASKET. The bolted ZHEJIANG GUTE joint design valve uses a contained, controlled compression, spiral wound type gasket.
4. ZHEJIANG GUTE BOLTING. The GUTE bolting is manufactured of alloy steel in accordance with the requirements of the applicable specifications such as API 602 and ASME B16.34.
5. 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. 6. 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
7. 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 ZHEJIANG GUTE. The stem is designed to the basic dimensional requirements of the applicable specifications such as API 602.

9. 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. 10. YOKE SLEEVE. The yoke sleeve is of forged stainless steel material having a high melting point and is resistant to wear and corrosion
