    Description

    Pressure Seal Bonnet PSB Cast Steel Gate Valve A216 WCB 

    Application:

    Oil and Gas, Petrochemical, Power, Energy Industry etc.

    Quick Details:

    1. Product: Pressure Seal Bonnet PSB Gate Valves

    2. Model: Z560Y,Z561Y,
    2. Pressure Seal Bonnet (PSB), Flexible Wedge Design
    3. Size Range: 2" - 20"
    4. Pressure Ratings: ANSI 1500LB / 2500#
    5. Materials Available in: Carbon Steel, A216 WCB,
    6. Various trim materials are available to suit different service conditions
    7. Actuator: Bevel Gear Operated

    8. Special Requirement: Nace Mr 0175

    9. Specail Testing: RT, LP, MT Inspection.

    Features:

    1. Bonnet Gasket Style

    Pressure seal design is used for Class 1500 gate valve.

    2. Packing Seal

    As usual, flexible graphite is used for packing material. PTFE or combined packing material can be also used if being requosted by the customer.

    3. Body and Bonnet Connection

    Class 1500 gate valves usually adopt pressure seal bonnet design

    4. Seat

    For carbon steel gate valve, the seat is usually forged steel. The seat sealing surface is overlaying welded with hard alloy specified by the customer. For Stainless steel gate valve, the seat is integral with body, or it can be machined directly after hard alloy welded.

    5. Disc Design
    NPS≥2 Gate valves are flexible wedge gate.

    6. Backseat Design

    All gate valves have backseat design. In most cases,the carbon steel gate valve is fitted with a renewable back seat. For stainless steel gate valve, the back seat is machined directly in the bonnet or be machined after welding.

    7. Stem Design

    The stem is integral forged design. The minimum diameter of the stem shall be as per the standard requirement.

    8 .Stem Nut

    Usually, the stem nut is made of ASTM A439 D2. It is also can be made of copper alloy or other materials if being requested by the customer.

    9. Operation

    Hand wheel or bevel gear box is usually used for gate valve operation.

    Standards

    Design and Manufacture: Cast steel gate valve to API 600 or API 6D;

    Inspection and Test: API 598, API 600 or API 6D.

    End flange dimension: ASME B16.5 (for NPS≤24)

    BW end dimension: ASME B16.25.

    Face to face and end to end: ASME B16.10.

    Pressure-temperature ratings: ASME B16.34.
