Pressure Regulation Valve for Vacuum Extraction Systems

Product Specifications

Technical details and manufacturing context for Pressure Regulation Valve

Definition

The Pressure Regulation Valve is a component used in vacuum extraction systems to control and stabilize internal pressure. It is part of the machinery and equipment manufacturing sector, specifically designed for integration into vacuum extraction units. The valve precisely regulates airflow to maintain a set pressure point, ensuring optimal vacuum performance and system safety during extraction processes. Its working principle involves adjusting the flow area or using a spring-loaded diaphragm mechanism that responds to pressure changes, opening or closing to maintain the desired pressure. The valve is available with a nominal diameter of 15–100 mm (ISO 6708), operating pressure of 1.0–1.6 MPa, and a pressure adjustment range of 0.1–1.0 MPa. It has a flow coefficient (Cv) of 2.5–100 (IEC 60534-2-1), leakage rate ≤0.01% of rated capacity (ISO 5208), and operating temperature of -20–80°C. Response time is ≤1 second, control accuracy ±0.5% of span, supply voltage 24 ±10% V DC (IEC 61131-2), power consumption 5–15 W, enclosure protection IP54–IP65 (IEC 60529), body material WCB/CF8M (ASTM A216/A351), seal material PTFE/FKM (ASTM D2000), and weight 5–50 kg. Materials on file include stainless steel, brass, and PTFE seals. These specifications are reference ranges; verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

The valve operates by sensing downstream pressure and adjusting its internal flow area. A spring-loaded diaphragm or similar mechanism compares the actual pressure to a set point. When pressure deviates, the diaphragm moves, causing the valve to open or close, thereby regulating airflow to restore the desired pressure. This feedback loop ensures stable vacuum conditions. The valve can be manually adjusted or equipped with an electric actuator for automated control. The response time is fast, typically under one second, to maintain tight control accuracy. The valve's design includes a tight shut-off to minimize leakage, and materials are selected for durability and chemical compatibility.

Frequently Asked Questions

What is the operating pressure range of this valve?

The operating pressure range is 1.0–1.6 MPa. Always verify the exact range for your specific model with the manufacturer.

What materials are used in the valve construction?

The valve body is available in WCB (carbon steel) or CF8M (stainless steel) per ASTM A216/A351. Seals are PTFE or FKM per ASTM D2000. Other materials on file include stainless steel, brass, and PTFE seals. Confirm material compatibility with your process media.

How does the valve maintain pressure?

The valve uses a spring-loaded diaphragm mechanism that senses downstream pressure. When pressure changes, the diaphragm moves to adjust the flow area, opening or closing to maintain the set point. This provides fast response and tight control accuracy.

What is the leakage rate and how is it tested?

The leakage rate is ≤0.01% of rated capacity, tested per ISO 5208 Class VI. This ensures tight shut-off. However, actual leakage may vary with installation and wear; verify with the supplier.
