Product Introduction
| Product Name | DN20 PN63 Flange End Handwheel Operation Gate Valve |
| Material | A105/F304/F316/F11/F51/F53/F55 |
| Pressure | 150LB/300LB/600LB/900LB/1500LB/2500LB/PN16/PN25/PN40/PN63/10K/20K |
| Size | 1/2 inch~ 2 inch（DN15~DN50) |
| End Connection | RF/RTJ/BW/SW |
| Working Temp | -196ºC~400ºC. |
| Mode of operation | Handwheel |
| Suitable Medium | Water,Natural Gas,Oil and some corrosive liquid |
| Features | Rising stem,OS&Y,Bolted Bonnet or Pressure Sealed,non-rising stem option |
Key Features:
Forged F304 Stainless Steel Construction: Compliant with ASTM A182 standards, offering superior corrosion resistance against acids, chlorides, and high-salinity media.
Pressure & Temperature Resilience: Rated for PN63 (Class 400, 6,900 PSI) with an operational range of -196°C to 550°C, ideal for LNG cryogenic storage, steam pipelines, and chemical processing.
Full-Bore Design: Minimizes pressure drop and ensures unrestricted flow for viscous or particle-laden fluids.
Advantages:
Zero Polymer Components: Eliminates risks of thermal deformation or chemical degradation in extreme environments.
20-Year Service Life: Validated by accelerated aging tests under cyclic thermal stress (ASTM E8/E21).
Key Features:
OS&Y (Outside Screw & Yoke) Mechanism: Isolates stem threads from media contact, coupled with a visual stem position indicator for real-time status monitoring.
Bidirectional Metal-Seated Wedge Disc: Precision-machined to API 600 standards, achieving zero leakage per API 598 testing under 63-bar differential pressure.
Fire-Safe Option: Optional API 607 certification ensures integrity during fire exposure (tested at 750°C for 30 minutes).
Advantages:
Maintenance-Free Sealing: Self-adjusting wedge design compensates for seat wear, extending maintenance intervals by 50%.
Emergency Readiness: Meets ISO 10434 requirements for critical shutdown applications in refineries.
Key Features:
EN 1092-1 RF Flange Ends: Pre-machined bolt holes and Ra 3.2µm surface finish ensure leak-tight gasket sealing (compatible with spiral-wound or PTFE gaskets).
Low-Torque Handwheel: Ergonomically designed gear ratio reduces operating force by 40% compared to standard valves (tested per MSS-SP-81).
Top-Mounted ISO 5211 Pad: Ready for actuator retrofitting without disassembly (e.g., pneumatic, electric).
Advantages:
Rapid Installation: Pre-aligned flange faces cut installation time by 30% in congested pipe racks.
Cost Efficiency: Manual operation eliminates energy costs, while top-entry design enables in-line maintenance without system shutdown.
Key Features:
Certifications: API 600 (gate valves), ASME B16.34 (pressure integrity), NACE MR0175 for sour service (optional).
Customization: Available with locking handwheel, extended stem for insulated lines, or cryogenic extended bonnet.
Advantages:
Global Regulatory Acceptance: Approved for offshore platforms (DNV-GL), chemical plants (ATEX/IECEx Zone 2), and power generation (ASME Section I).
Versatile Applications:
Oil & Gas: Wellhead isolation, pipeline pigging.
Energy: Superheated steam control, turbine bypass.
Chemicals: Corrosive acid shutoff, reactor feed lines.
