â… . Product Introduction
â…¡. Product Features
- Excellent Sealing Performance
The flat gate design, paired with resilient or metal-to-metal sealing surfaces, ensures tight shutoff even under high differential pressures, preventing leakage of critical media. Double ram configurations provide enhanced sealing reliability for demanding applications.
- Low Flow Resistance
When fully open, the flat gate aligns with the pipeline’s inner diameter, creating an unobstructed flow path that minimizes pressure drop and energy loss.
- Flexible Configuration Options
Offers rising-stem (visual position indication) and non-rising-stem (space-saving) designs, with optional diversion holes for pipeline cleaning and pigging operations.
- Wide Pressure and Temperature Range
Capable of operating at pressures up to 10.0 MPa (and higher for API-compliant wellhead models) and temperatures from -29°C to 425°C, adapting to both cryogenic and high-temperature service conditions.
- Durable Construction
Manufactured from high-quality carbon steel, stainless steel, or alloy steel, the valve body and gate resist corrosion, erosion, and wear, ensuring a long service life even in harsh media environments.
- Compliance with Industry Standards
Meets international standards such as API 16A (for wellhead valves), GB, and DIN, ensuring compatibility with global pipeline systems and regulatory requirements.
