1/4" Gas Ball Valve (PN20, F-F BSP): EN 331 Approved for Professional Gas Control

Secure, Reliable, and Precise Gas Flow Control for Professional Applications

When it comes to gas installations, safety and reliability are paramount. You need components that not only meet the highest standards but also offer effortless operation and long-term performance. Standard valves might not provide the specific approvals or robust features required for demanding gas control.

This 1/4" Gas Ball Valve is engineered to deliver uncompromised safety and efficiency for your gas lines. GAS Approved to EN 331 standards, it ensures compliance and peace of mind. With a reliable PN20 pressure rating and industry-standard threaded female BSP connections, it guarantees a secure and leak-tight seal. Its full bore design minimizes flow resistance, ensuring optimal gas delivery, while the user-friendly butterfly handle allows for quick, precise, and easy operation. This valve is the ideal choice for professional gas control applications where reliability and safety are non-negotiable.

Key Features & Benefits

• GAS Approved (EN 331): Fully certified to European standard EN 331, guaranteeing compliance and suitability for gas installations. This is a critical safety and regulatory compliance feature.

• Reliable Pressure Rating (PN20): Designed to withstand pressures up to 20 bar (PN20), ensuring strong durability and safety in typical gas systems.

• Standard 1/4" Size: Common quarter-inch sizing for broad compatibility with typical gas piping setups.

• Female BSP Connections: Features precise female BSP (British Standard Pipe) threaded connections for straightforward and secure integration into existing plumbing systems.

• Full Bore Design: Allows gas to flow through with minimal restriction, ensuring maximum flow rate and preventing pressure drops for efficient system performance.

• Effortless Butterfly Handle: Provides simple, quick, and precise quarter-turn operation for instant ON/OFF control, even in tight spaces.

• Reliable Sealing: Engineered for superior leak prevention, offering a dependable and safe seal for gas applications.

• Durable Construction: Made from robust materials designed to withstand the corrosive nature of gas and the demands of continuous operation.

How a Gas Ball Valve Works

A ball valve operates using a rotating ball with a bore (hole) through its center. When the valve is open, the bore is aligned with the pipe, allowing gas to flow directly through with minimal obstruction (full bore). When the butterfly handle is turned 90 degrees, the bore rotates to be perpendicular to the pipe, blocking the flow and providing a tight shut-off. This simple quarter-turn mechanism makes ball valves highly effective for quick on/off control and reliable sealing, making them superior to gate or globe valves for gas isolation where tight shut-off is critical.

Important Installation & Safety Notice

Installation of this gas ball valve must ONLY be performed by a qualified, Gas Safe Registered Engineer (or equivalent certified professional in your region) in strict accordance with all local gas regulations, safety codes, and the manufacturer's instructions. Always ensure the main gas supply is turned off and depressurized before any work is carried out. Improper installation can lead to dangerous gas leaks, fire, explosion, or severe injury.

Frequently Asked Questions (FAQs)

Q1: What does "EN 331 Approved" mean for this valve?

A1: EN 331 is a European standard for manually operated valves for gas installations in buildings. Being EN 331 approved means this valve has been tested and certified to meet stringent safety and performance requirements for use with gas, ensuring it's safe and reliable for its intended purpose.

Q2: What is the significance of the "PN20" pressure rating?

A2: PN20 indicates that the valve is rated for a Nominal Pressure of 20 bar. This is a robust pressure rating, making it suitable for standard gas applications.

Q3: Can I install this valve myself?

A3: No. Due to the inherent dangers of gas, all installations, repairs, or replacements of gas components, including this valve, must be carried out by a fully qualified, Gas Safe Registered Engineer (or equivalent certified professional in your country).

Q4: What does "full bore" mean for a ball valve?

A4: "Full bore" means the internal diameter of the valve's bore (the hole through the ball) is the same or very close to the internal diameter of the connected pipe. This design minimizes flow restriction, ensuring maximum gas flow rate and reducing pressure drops across the valve.

Q5: What types of gas is this valve compatible with?

A5: This valve is designed for use with Natural Gas, LPG (Propane/Butane), and Manufactured Gas, in line with EN 331 standards. Always verify compatibility with your specific gas type and local regulations.
