Pronom by Ayor, the pioneering benchmark in pressure reducers, goes beyond the standard.

• Precise pressure control: Pressure reducers and regulators pre-set to 3 bar to protect installations and optimise comfort of use.
• A complete range for every configuration: Diaphragm, cartridge or piston technologies, tailored to installation needs and site constraints, from residential to small multi-unit buildings.
• A sustainable and responsible solution: Eco-designed products built to limit consumption, protect equipment and guarantee long-term performance.

Developed to guarantee reliability, durability and sealing performance, this range of valves meets the demands of professional installations.

• A certified benchmark: The market's first NF-certified valve, designed to secure installations and meet professional expectations.
• Enhanced, maintenance-friendly sealing: Double sealing via gland packing and O-ring, for excellent reliability and easy maintenance.
• Components built to last: Limescale-resistant chrome-plated brass ball, Teflon seat for low and consistent operating torque, and a moisture-resistant stainless steel handle.
• Compliant with European standards: Low-nickel-content CW617N brass body, for controlled material quality.

Designed and developed by our engineers to secure drinking water networks, this range of backflow prevention valves guarantees reliable protection for installations.

• Fully French-made: Valves designed, developed and manufactured in France, at our Rousset plant.
• Material quality compliant with health requirements: 4MS-grade brass body, suited to drinking water networks.
• Versions adapted to every installation: EA-type valves with single or double drain, to meet network protection needs.
• Easy installation for every configuration: Short or long models with double swivel nuts, to simplify connection and adapt to space constraints.
