ball valves for gas

How can safety and lasting reliability be ensured in gas installations, where the integrity of each individual component is critical for risk prevention? The answer is in the meticulous design, choice of certified materials, and a production process without compromise. In this context, gas ball valves represent the ultimate shutoff and safety device that ensures total flow control and security for professionals and end users.

Novasfer, with its long-standing experience in manufacturing brass components, designs and produces a complete range of gas valves that embody the highest standards of quality and regulatory compliance. Every gas valve in our catalog is the result of precision engineering, designed to deliver excellent performance ensuring a hermetic seal and consistent operability over time.

Technical and construction features of Novasfer gas valves

The superiority of a gas ball valve is measured in its construction details and the quality of materials employed. Novasfer’s approach to production combines technological innovation with deep knowledge of materials and industry regulations, ensuring a final product that excels in every aspect.

The choice of brass: a guarantee of resistance and durability

The body and main components of our gas valves are made of the highest quality brass produced in Italy, a metal alloy chosen for its exceptional properties. Brass ensures extraordinary corrosion resistance—a critical factor in installations where condensation or impurities may be present. Furthermore, its mechanical robustness assures long operational life even under intensive use conditions and at elevated pressures. Precision machining, performed with state-of-the-art CNC machinery, allows for minimal tolerances and perfect surfaces—essential for an impeccable seal. The entire production chain is an example of our know-how. Discover all the brass components produced by Novasfer.

The heart of the gas valve: ball, stem, and sealing systems

The functional heart of every screwfix gas isolation valve is the ball-stem-seals system. The balls used in Novasfer valves are machined with ultra-high-precision surface finishes and often chrome-plated to reduce friction and wear. The stem is designed with a blow-out proof system for maximum safety, preventing it from being expelled from the valve body even in case of abnormal overpressures. The seals are made from materials specifically selected for gas applications, such as virgin PTFE (polytetrafluoroethylene) and NBR or FKM O-rings, chosen to guarantee perfect chemical compatibility, a low coefficient of friction, and a certified hermetic seal over time, even in the face of temperature and pressure variations.

Operating levers: ergonomics, safety, and identification

The operating lever is not a simple accessory, but a fundamental component for safety and usability. Our 15mm gas valve is equipped with steel or aluminum levers, designed to be ergonomic and robust. The PVC coating or epoxy powder coating not only protects against corrosion, but also allows for clear visual identification thanks to the yellow coloring—the industry standard for gas lines. Many models are also prearranged for the installation of padlock locking systems, an essential feature for securing installations during maintenance operations.

Types of gas valves for every installation need

The versatility of a catalog is measured by its ability to offer the right solution for every specific application context. The Novasfer range of gas valves has been developed to cover all system requirements, from residential to industrial.

Gas ball valves for natural gas and LPG: compliance and certifications

The handling of combustible gases requires compliance with stringent regulations. Our gas ball valves for natural gas and LPG are designed, produced, and tested in accordance with the most severe European standards, such as EN 331. This certification ensures that the gas valve has passed rigorous tests for sealing, mechanical resistance, durability, and operating torque, guaranteeing its suitability for use in gas installations with pressures up to 5 bar (MOP 5). Choosing a certified Novasfer product means making a responsible and safe choice, protecting both the installation and the people who depend on it.

The gas valve boiler and valves

Specific applications require specific components. The boiler gas valve is a critical component that must guarantee absolute reliability for the supply of the heat generator. Our models are compact, robust, and easy to install, ensuring safe and accessible shutoff.

Installation and maintenance: best practices for maximum safety

A high-quality gas valve expresses its full potential only when installed and maintained correctly. It is essential that the installation of any gas valve be performed by qualified personnel, in compliance with current regulations. The use of thread sealants approved for gas use and adherence to tightening torques are crucial steps for preventing leaks. Although Novasfer gas valves are designed for minimal maintenance, it is recommended to perform periodic operations (at least a couple of times per year) to verify correct functionality and prevent the ball from seizing, thus ensuring operational readiness in case of need.

In conclusion, the choice of a gas valve cannot be left to chance. It is an investment in safety, efficiency, and peace of mind. The Novasfer range offers designers, installers, and distributors a complete, certified solution, the result of decades of experience in brass processing and a constant commitment to innovation.
