01 Overview

The new series has been developed to meet the requirements of modern systems, characterized by pressures up to 50 bar and temperatures up to 150°C, ensuring reliability and consistent performance.

01

Castel continues to strengthen its portfolio of safety devices with the introduction of the 3030 series safety valves, specifically designed for refrigeration and air conditioning systems using hydrocarbon (HC) refrigerant, classified as A3.

Modern refrigeration systems increasingly operate under demanding conditions, combining high working pressures and elevated discharge temperatures. The 3030 series has been engineered to meet these challenges, offering set pressures up to 50 bar and operating temperatures up to 150°C, ensuring reliable protection of the system.

02

Thanks to their compact design and the use of high- performance materials, the 3030 valves represent a dependable safety solution for a wide range of installations. Their set pressure range from 8 to 50 bar provides significant operational flexibility, allowing installation both in low-pressure and high-pressure sections of the system.

A key feature of the series is its repeatable performance: after operation, the valve maintains the original calibration conditions, guaranteeing long-term reliability and system safety.

03

With the development of the 3030 series, Castel confirms its role as a reliable partner for systems using natural and low-GWP refrigerants, providing an affordable and robust safety solution suitable for many refrigeration and air conditioning applications.
