Technical Data Sheet

The 04556 Series is the ideal solution for those seeking in-line unidirectional check valves with piston specifically designed for the most demanding professional applications.

Manufactured entirely from AISI 316 stainless steel, these valves offer superior resistance to both corrosion and high pressure, making them perfect for systems operating in aggressive environments or under extreme working conditions.
At the heart of the 04556 Series is a robust and compact body designed to ensure reliable and long-lasting performance even under intensive operating cycles. The quality of the materials used guarantees that the valve maintains high performance over time, minimizing the risk of leakage or sudden failure.

This series stands out for its maximum application flexibility, thanks to gaskets available in FKM and PTFE, which cover a wide range of operating temperatures: from -10°C to +215°C (+14°F ÷ +419°F) with FKM and from -150°C to +230°C (-238°F ÷ +446°F) with PTFE. Performance in terms of pressure is among the best in the industry, reaching 420 bar (6092 psi) for sizes from 1/8" to 1/2", 300 bar (4351 psi) for 3/4", 250 bar (3626 psi) for 1", 1”1/4, and 1”1/2, and 210 bar (3046 psi) for 2".
The check valves of the 04556 Series are supplied as standard with ISO 228 (BSP) cylindrical gas threads, but are also available in NPT version (ANSI B 1.20.1-1983) for maximum compatibility with any system, whether national or international.

Each product is CE certified, ensuring compliance with the strictest European standards for quality, reliability, and safety.
