1. Product Overview
The Pressure Balance Type Oil Sealing Plug Valve is engineered for demanding industrial applications requiring zero leakage and pressure stability in oil, hydrocarbon, and hydrocarbon-based media systems. Its innovative "inverted" (top-entry) design and pressure-balanced structure minimize operational torque while ensuring reliable sealing even under extreme pressure differentials.
2. Key Features & Technical Advancements
- Pressure-Balanced Design:
- Reduces operational torque by up to 50% compared to conventional plug valves, enabling easier manual operation or automation.
- Maintains stable sealing performance under fluctuating pressures (150-900 Lb).
- Oil Sealing Technology:
- Specialized elastomeric or thermoplastic seals lubricated by system media, preventing dry operation and extending service life.
- Suitable for media with lubricating properties (e.g., crude oil, diesel, hydraulic fluids).
- Inverted (Top-Entry) Structure:
- Facilitates in-line maintenance without disassembling the valve body or pipeline.
- Reduces downtime and maintenance costs.
- Fire-Safe Design:
- Metal-to-metal secondary sealing for emergency fire conditions (API 607/API 6FA compliant).
- Anti-Blowout Stem:
- Ensures operator safety by preventing stem ejection under extreme pressure.
