Highest quality and durability, complete traceability and fast availability thanks to our state-of-the-art logistics: these are the arguments in favour of our standard Nova Swiss high-pressure technology products up to 10,000 bar.
Reliable and Stable
Nova Swiss needle valves offer the highest degree of safety and reliability, even under challenging operating conditions. The valves can be installed in both directions and provide an effective seal for both gaseous and liquid media. The heart of the valve consists of a specially shaped valve seat and a two-piece, non-rotating stem. Erosion of the stem is thereby avoided.
The pressure-resistant parts are made of high-quality, corrosion-resistant stainless steel. Every single valve body is certified by us. For applications that are subject to particularly strict quality standards, we offer complete traceability of all our pressure-bearing parts. Nova Swiss high-pressure valves are supplied complete with screw fittings.
Automation and Monitoring
High-pressure systems can be automated easily and effectively by using Nova Swiss valves with air-operated actuators. The valve bodies and packing systems are identical to those in the manual valves and provide the same benefits. The extremely robust and reliable air-operated piston actuator is available in two versions:
Nova Swiss extreme-temperature valves for high-pressure gas applications are designed to operate at temperatures ranging from -200°C to +300°C thanks to a special extension adapter.
Nova Swiss offers high-performance safety valves engineered to reliably protect high-pressure circuits in hydrogen applications.
Available with set pressures tailored to HSL35 and HSL70 service levels, our valves ensure safe and consistent operation even under demanding conditions. All wetted components, temperature ranges, and connection types are carefully verified and validated for full compatibility.
For enhanced safety, the exhaust vent port is pipeable – allowing for controlled venting and reduced risk in high-pressure environments. Each valve is precisely set to customer specifications, fully certified, and secured with a factory lead seal.
Valve Design according to CE-Standards and ATEX Safety valve in accordance with
CE standards ATEX certified:
Safe and reliable, direction-dependent
Nova Swiss check valves ensure an ideal degree of leak-tightness for both gases and liquids thanks to the use of bonded metal/plastic seats. Our check valves are characterized by excellent flow rates and maximum reliability — both at low and high pressures. The replaceable seats allow simple and cost-efficient maintenance. Our high and low-pressure check valves are supplied complete with screw fittings.
Block Valves with Venting
NOVA SWISS block valves with venting (Block and Bleed — BBV) as well as double-block valves with venting (DBV) provide maximum safety in confined spaces.
Their design allows measuring instruments and/or pressure gauges to be disassembled in an unpressurized state during running operation. Additional features include a reduction of potential leakage points and the number of screw connections to a minimum. The BBV is available in 1/4" and 3/8" versions, the DBV in 1/4", 3/8" and 9/16".
Some of our block valves are also available in custom designs on request.
Nova Swiss fittings ensure leak-free screw connections for tube components. They give you the security of using a simple yet reliable screw joint system. Our screw fittings can be installed and removed as often as required. Their faceted edges make handling easier and reduce the risk of injury. All fittings are supplied complete with screw connections.
Nova Swiss supplies a wide range of adapters, screw fittings and couplings, which are available in different connection sizes and make virtually any conceivable type of screw connection and interface possible.
Nova Swiss high-pressure couplings feature metallic seals and can be connected as often as required. In addition to the standard version, we offer our Vibro Tight coupling that is designed to withstand large vibrations.
Effective protection against overpressure
Nova Swiss safety heads provide dependable safety and protection in the event of overpressure. The safety heads can be equipped with different bursting discs for a range of burst pressures. The bursting discs can be replaced easily and cost-effectively. Safety heads are supplied complete with screw fittings.
For leak-free transport of gases and liquids
Nova Swiss high-pressure pipes and nipples are made from stainless steel and either straightened or bent to custom angles and autofrettaged as required. They are seamless, cold drawn and hardened to ensure high strength and corrosion resistance. During the manufacturing process, the chemical composition and mechanical values of the material are tested and recorded in accordance with strict criteria.
Nova Swiss has successfully established itself as a supplier of components used in H2 technology. Whether for H2 filling stations the complete high-pressure range, piping all around the Electrolyser or low-pressure valves on the fuel cell in the vehicle, all requirements can be met. In the research and development of the fields of application of renewable energy sources, we see ourselves as a competent and solution-oriented partner. In addition to individual parts we also offer complete assemblies which are pre-assembled, tested and prepared for installation.
The new N-Line stands for precision, safety and the highest quality in high pressure technology. Designed specifically for liquid applications, it offers high performance solutions for the most demanding applications.
Our configurator makes it quick and easy to find the right high pressure component for your application. Select individual specifications and you will get a tailor-made solution - precise, efficient and reliable.
Our strengths: development, production and quality assurance. With technical expertise and experience, we guarantee the highest standards of quality, safety and sustainability.
