SIM Italy has been dedicated to precision, long-life brass valves since 1957. Today, with two fully automated manufacturing sites in San Maurizio d’Opaglio and Pogno, Italy, the company serves more than 77 countries through its distribution network and reports annual turnover exceeding €50 million.
Quality Infrastructure & Technical Compliance
All machining, assembly, testing, and packaging at SIM follow four integrated international standards: ISO 9001:2015 (Quality), ISO 14001:2015 (Environmental), ISO 45001:2018 (Occupational Health & Safety), and ISO 50001:2018 (Energy Management). This unified framework reduces production defects, extends product life, and minimizes environmental impact.

2025 Innovation: Cim 778 Thermostatic Balancing Valve
A smart solution for domestic hot-water (DHW) recirculation loops in high-rise buildings:
- Field-adjustable setpoint: 95–140°F (35–60°C).
- Enables thermal disinfection (pasteurization) at high temperature without system shutdown.
- Thermostatic element is outside the flow path to reduce scaling and fouling.
- No dependence on power, sensors, or software; simple periodic maintenance.

Key Selection & Design Notes
- Brass alloy CW617N in bodies and internal segments helps ensure resistance to dezincification under high pressure.
- In four-pipe HVAC systems, pairing the Cim 778 with a two-way ball valve can reduce overall pressure drop by up to 18%.
- For municipal gas lines, choose models with AISI 316 stainless-steel balls and BSP Taper threads to EN 10226.
- In solar-thermal projects, the 150 °C rating of SIM needle valves provides a safety margin for summer stagnation.
Versatile Use Across Industries
- Oil & Gas: Up to 40 bar with PN40 flanged connections for process lines.
- Food & Beverage: PTFE–bronze sealing with WRAS approval for potable service.
- Smart Agriculture: Integrate motorized ball valves with BACS per UNI ISO 52120 to reduce water use in drip irrigation.
- Green Buildings: No-Lead models with NSF/ANSI 61 support LEED v4 credits (Materials & Resources).
Available worldwide through authorized distributors, with technical consultation and after-sales support provided by certified partners.
