High-Performance Pilot-Operated Safety Valve for Gas Applications – 8R10 Size, 18MPa Set Pressure

Product Overview
Our pilot-operated safety valve (Model: POSV-8R10-18MPa) is an innovative product specifically designed for high-pressure gas applications, having passed rigorous testing—with a test pressure of 22MPa and 1,000 hours of trouble-free continuous operation. It is suitable for the oil and gas, chemical, and energy industries, ensuring system safety and efficiency. The 8" inlet and 10" outlet design optimizes the flow path, minimizing energy loss to the greatest extent.

Application Scenarios
This valve is applicable to the following high-pressure gas systems:
● Oil & Gas Platforms: Used for wellhead control and pipeline pressure relief, handling high-flow gas (e.g., flow rate up to 500 m³/min at 18MPa).
● Chemical Process Equipment: Provides reliable overpressure protection in reactors and storage tanks, compatible with media such as natural gas and nitrogen.
● Power Plants & Compression Stations: Suitable for turbine and compressor systems, withstanding high temperatures of 120°C to ensure continuous operation.
Data Support: According to industry data, large-diameter valves (such as 120mm flow path) can reduce pressure drop loss by 30% and improve system efficiency by 10-15% in high-pressure applications.

Technical Advantages & Data Analysis
Compared with traditional spring-loaded valves, our pilot-operated safety valve outperforms in multiple aspects, with its performance verified by test data and industry standards (such as ASME and API):
Installation Height Advantage
● Data Comparison: Spring-loaded safety valves typically require an installation height of 1.5-2.0 meters to accommodate the spring assembly, while our pilot-operated design only needs 1.0 meter (reducing height by approximately 40%).
● Advantage: Saves space, facilitates installation in compact facilities (such as offshore platforms or modular plants), and lowers overall structural costs. Tests show this can shorten installation time by 25%.
Backpressure Resistance Capacity
● Data Comparison: Spring-loaded valves may fail or experience reduced accuracy when backpressure exceeds 5MPa, while our pilot-operated valve can withstand backpressure up to 10MPa (based on test results, the impact of backpressure changes on set pressure is less than ±2%).
● Advantage: Enhances system flexibility, adapts to variable working conditions (such as downstream pressure fluctuations), reduces the need for additional pressure relief equipment, and saves costs by 15-20%.
Reaction Force Control
● Data Comparison: Spring-loaded valves generate high reaction force when opening (e.g., up to 50kN at 18MPa), which may cause pipeline vibration or equipment damage. Our pilot-operated design reduces reaction force to 20kN (a 60% reduction).
● Advantage: Extends the service life of valves and pipelines, reducing maintenance frequency. Test data shows that lower reaction force can increase system operational life by more than 30%.
Overall Performance Data
● Leakage Rate: <0.01% at set pressure (exceeds the industry standard of 0.1%).
● Opening Time: <100 milliseconds, ensuring rapid response to overpressure events.
● Material: Made of high-strength alloy steel, corrosion and high-temperature resistant, with a service life of over 10 years.

Why Choose Pilot-Operated Design?
● Reliability: Pilot-operated valves use a pilot piston to control the main valve, avoiding spring fatigue issues, with a repeat accuracy of ±1% in tests.
● Cost Efficiency: The initial investment may be slightly higher, but the Return on Investment (ROI) can be achieved within 2 years through reduced downtime and maintenance.
● Market Validation: Successfully applied in multiple international projects, with a customer satisfaction rate of over 95%. Contact us for case studies and customized solutions—we are committed to delivering the best products at the lowest cost to support your project success!

Competitive Edge Over Spring-Loaded Valves
● No Spring Fatigue: Controlled by pilot pistons, eliminating spring wear that causes accuracy drift and frequent replacements.
● Space and Cost Savings: 40% lower installation height reduces structural costs; 60% less reaction force extends pipeline service life.
● Flexible Backpressure Handling: Tolerates up to 10MPa backpressure, adapting to variable working conditions without additional equipment.
● Superior Precision: <0.01% leakage rate and <100ms opening time exceed industry standards, minimizing operational risks and downtime.
