Main Parameters
• Nominal Pressure: PN16～PN160, suitable for high-pressure and high-temperature high-pressure conditions
• Nominal Diameter: DN15～DN200, mainly for small-diameter high-pressure pipelines
• Operating Temperature: Carbon steel -29℃～425℃; Stainless steel/alloy steel can withstand temperatures above 600℃
• Valve Body Material: A105, 304, 316L, F11, F22, etc., integrally forged materials
• Sealing Grade: Hard seal and soft seal options are available, with stable sealing performance and strong pressure resistance.
Structural Forms
1. Wedge-type single gate valve: Simple structure, high cost-effectiveness, strong versatility, mostly used in conventional steam and oil pipelines.
2. Wedge-type double gate valve: Automatically compensates for sealing gaps, resistant to high temperature and pressure, and provides long-lasting and stable sealing.
3. Integral welded type: No external leakage points, robust structure, creep resistant, mostly used in power plants and high-temperature and high-pressure special equipment.
Core Advantages
• Integral forging process, high valve body density and strength, resistant to high pressure, impact, and cracking.
• Straight-through full-bore flow channel, minimal flow resistance, no pressure loss in media transport.
• Bidirectional flow, no installation direction restrictions, convenient on-site pipeline installation.
• Excellent temperature and pressure resistance, suitable for harsh conditions such as high-temperature steam and high-pressure oil and gas.
• Compact structure, uniform wall thickness, good sealing performance, low leakage risk, and long service life.
