FILLING VALVE FOR KHS

Pressure Filling Valve: Efficient High-Pressure Fluid Control Solution

A Pressure Filling Valve is a precision-engineered device designed to regulate and control the flow of liquids or gases into containers, tanks, or pipelines using external pressure. Unlike gravity-fed systems, pressure filling valves are ideal for applications requiring high-speed filling, accurate volume control, and operation under elevated pressure conditions. These valves are widely used in industries such as oil and gas, chemical processing, pharmaceuticals, food and beverage, and automotive manufacturing.

How It Works

Pressure filling valves operate by utilizing an external pressure source (e.g., pumps or compressed air) to force fluids into a target container. The valve opens when triggered by a control system or manual input, allowing pressurized media to flow through. Once the desired fill level or pressure is reached, the valve closes automatically, ensuring precise and repeatable results. Advanced models integrate solenoid actuators, pressure sensors, or programmable logic controllers (PLCs) for fully automated operations.

Key Features & Specifications

1. Pressure Range:

• Standard models: 0.5–50 bar (7–725 psi).

• High-pressure variants: Up to 100 bar (1450 psi) for specialized industrial uses.

2. Materials:

• Body: Stainless steel (SS 304/316), brass, or aluminum for corrosion resistance.

• Seals: PTFE, EPDM, or Viton to ensure compatibility with aggressive chemicals or high temperatures.

3. Connection Types:

• Threaded (NPT, BSP), flanged, or tri-clamp connections.

• Common sizes: 1/4" to 4" (DN8 to DN100).

4. Temperature Tolerance:

• Standard: -20°C to 150°C (-4°F to 302°F).

• High-temp variants: Up to 200°C (392°F) with specialized seals.

5. Flow Rate:

• Adjustable via orifice size, typically 10–5000 liters per minute (LPM) depending on valve design.

6. Certifications:

• Compliant with ASME B16.34, ATEX (for explosive environments), FDA (food-grade applications), and ISO 9001.

Applications

1. Oil & Gas:

• High-pressure filling of fuel tanks, lubricants, or hydraulic fluids.

2. Chemical Industry:

• Safe transfer of corrosive liquids (acids, solvents) under controlled pressure.

3. Pharmaceuticals:

• Sterile filling of APIs (active pharmaceutical ingredients) or vaccines in cleanroom environments.

4. Food & Beverage:

• Carbonated beverage bottling, where pressure prevents CO2 loss during filling.

5. Automotive:

• Coolant or brake fluid dispensing in assembly lines.

Advantages

• Precision: Achieves ±1% volume accuracy with closed-loop control systems.

• Speed: Reduces cycle times by 30–50% compared to gravity-based methods.

• Versatility: Handles liquids, gases, and viscous media (e.g., adhesives, syrups).

• Safety: Built-in pressure relief valves prevent over-pressurization.

• Durability: Robust construction ensures longevity in harsh operating conditions.

Selection Guide

When choosing a pressure filling valve, consider:

• Media Type: Ensure material compatibility (e.g., PTFE seals for acids).

• Operating Pressure: Match valve rating to system requirements.

• Automation Needs: Opt for solenoid or pneumatic actuation for integration with PLCs.

• Hygienic Requirements: Specify electropolished surfaces and CIP/SIP capabilities for sanitary applications.
