Nova Swiss needle valves offer a high 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.

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: ATO (air-to-open), opens with compressed air. ATC (air-to-close), closes with compressed air.

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 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.

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.
