Flat gate valve without diversion hole

产品概览

The Flat Gate Valve without Diversion Hole is a robust and reliable solution designed for high-pressure, high-temperature applications in oil and gas pipelines, water distribution, and industrial processes. Featuring a flat gate design and no diversion hole, it ensures minimal pressure drop, tight sealing, and smooth operation, making it ideal for systems requiring full-bore flow and zero leakage.

应用

石油和天然气: Pipeline isolation and wellhead control.
Water Distribution: Mainline isolation and flow control.
Industrial Processes: High-pressure fluid handling in chemical and petrochemical plants.
Power Generation: Steam and feedwater isolation in power plants.

主要功能

Flat Gate Design

• No Diversion Hole: Ensures full-bore flow with minimal pressure drop.
• Tight Sealing: ANSI Class VI leakage rates for critical shut-off applications.
• Smooth Operation: Low operating torque due to flat gate design.

Valve Construction

• 车身材料: Carbon steel (WCB), 316L Stainless Steel (CF8M), Duplex (UNS S32205).
• Gate Materials: 13% Cr stainless steel, Stellite 6, or nickel-plated carbon steel.
• 密封件: Graphite, PTFE, or metal-to-metal sealing (-40°C to 450°C).

Flow Characteristics

• Full-Bore Design: Zero flow restriction for maximum efficiency.
• 流量系数 (Cv): 500–5000 (DN50–DN600).
• Pressure Drop: Minimal due to streamlined flow path.

Operational Features

• Low Torque Operation: Smooth opening and closing with minimal effort.
• Bidirectional Sealing: Effective sealing in both flow directions.
• Fire-Safe Design: API 607 certified for fire-safe applications.

运行优势

• Tight Sealing: ANSI Class VI leakage rates for critical applications.
• Low Torque: Smooth operation with minimal effort.
• Fire-Safe: API 607 certified for fire-safe applications.

Comparison with Slab Gate Valves

Selection Guidelines

High Pressure: Opt for Class 1500 or 2500 for extreme conditions.

Corrosive Media: Choose 316L body with Stellite 6 trim.

High Cycling: Nickel-plated gate for 10,000+ cycles.

Fire-Safe Applications: Select API 607 certified valves.
