Product Description

Product Description

Standards:
Design and Manufacture: Cast steel gate valve to AP| 600 (ISO 10434) or API 6D; Cast stainless steel gate valve to API 603 or API 600;
Forged steel gate valve to API 602.
Inspection and Test: API 598, API 600, or API 6D.
End flange dimension: ASME B16.5 (for NPS=24), ASME B16.47 series B. API 605 or ASME B16.47 series A. MSS SP-44 (for NPS > 24).
BW end dimension: ASME B16.25.
Socket-weld dimension: ASME B16.11.
Face to face and end to end: ASME B16. 10.
Pressure -temperature ratings: ASME B16.34

Gasket of Cover Flange:
Carbon steel or stainless steel + flexible graphite combined gasket is used for Class 150 gate valve; Stainless steel + flexible graphite wounded gasket is used for Class 300 gate valve; Stainless steel + flexible graphite wounded gasket is used for Class 600 gate valve, and ring joint gasket is also optional for Class 600 gate valve; Ring Joint gasket is used for Class 900 gate valve; Pressurized seal design is used for Class 1500~ Class 2500 gate valve.

Packing Sealing:
Molded flexible graphite is used for packing material. PTFE or combined packing material can be also used if requested by the customer. The internal surface of the stuffing box, of which area is contacted with the packing, is of excellent finish (Ra 3.2 u m). The stem surface, in contact with the packing, should be rolled and pressed after being precisely machined, so as to reach a high finish and compactness (Ra 0.8 um) and ensure the reliable tightness of the stem area.

Body and Bonnet Connection:
The body and bonnet of Class 150 ~ Class 900 gate valves are usually connected with studs and nuts. The body and bonnet of Class 1500~ Class 2500 gate valves are usually of pressurized seal design.

Belleville Spring Loaded Packing Impacting System:
It being requested by the customer, the Belleville spring-loaded packing impacting system can be adopted to enhance the durability and reliability of the packing seal.

Actuation:
The hand wheel or gearbox is usually used for gate valve actuation. Chain wheels and electric actuators can be also used for gate valve actuation if requested by the customers.

Design of Disc:
Gate valves with NPS≥2 are wedge flexible gates; Gate valves with NPS < 2 are wedge solid gates.

Back Seating Design:
All our gate valves have the back seating design. In most cases, the carbon steel gate valve is fitted with a renewable back seat. For the stainless steel gate valve, the back seat is machined directly in the bonnet or is machined after welding. When the gate valve is in a fully open position, the sealing of the back seat can be very reliable. However, as per the requirement of API 600, it is not advisable to add or change packing by means of back seating when the valve is pressure-containing.

Stem Design:
The stem is of integral forged design. The minimum diameter of the stem shall be per the standard requirement. The connection of the stem and disc is T type. The strength of the connecting area is bigger than that of the T-threaded part of the stem. The strength test of that area conforms to API 591.

Stem Nut:
Usually, the stem nut is made of ASTM A439 D2. It is also can be made of copper alloy if requested by the customer. For large sizer! gate valves (NPS 10 for Class 150, NPS 8 for Class 300, NPS 6 for Class 600, NPS 5 for Class 900), rolling bearing is fitted at the two titles, s the stem nut in order to minimize the open and close torque of the gate valve.

Seat:
For carbon steel gate valves, the seat is usually forged steel. The sealing surface of the seat is spray welded with hard alloy specified by the customer. The renewable threaded seat is used for NPS 10 gate valves, and the welded seat can be also optional if requested by the customer.
A welded-on seat is used for NPS≤ 12 carbon steel gate valves. For Stainless steel gate valves, an integral seat is usually adopted, or a hard alloy directly integrally. Threaded or welded on seat is also optional for stainless steel gate valve if being requested by the customer.


Special Gate Valve:
Besides the common gate valves, Our company also makes cryogenic gate valves, Jacketed Gate valves, Bellow Sealed Gate valves, Extension Stem Gate valves for underground application, etc.
