ITAP, a flagship of Italy’s brass valve industry, ships durable products built on fully automated manufacturing, multi-stage quality control, and EN 12165 alloys—conforming to CE and ISO 9001. This approach boosts safety and service life in piping systems while reducing maintenance for building and industrial projects.
York Spring Check Valve — the beating heart of water networks
ITAP’s York Spring Check Valve is a frontline defense against backflow and pressure fluctuations. A forged-brass body, AISI 302 stainless spring, and NBR sealing make it ideal for pressures up to 12 bar and working temperatures from –10 to +110 °C. Install it between pump and tank, on boiler supply/return lines, or at an underfloor-heating manifold inlet to stabilize hydraulics, prevent pump cavitation, and extend equipment life.

Competitive advantages for projects
- Lower energy loss: Low-pressure-drop design improves circulation and reduces pump energy.
- Easy to install & service: Precision ISO 228 threads with factory-installed PTFE sealing accelerate commissioning.
- Environmental compliance: Low-lead alloys in line with EU Directive 2002/95/EC (RoHS).
- Wide application coverage: From hospital HVAC to agricultural drip irrigation, ITAP scales across sectors.
Quick selection guide
- Define the fluid: cold water, hot water, mildly corrosive media, or compressed air.
- Match project pressure to valve class (PN 12 or PN 25).
- Check operating temperature; for steam-heating, specify special pressure reducers and strainers with Viton rings.
- Consider space: choose compact models such as spring check valves for tight installs.
Essential installation & operation notes
- Align flow with the arrow on the body; reverse installation can cause water hammer and disc damage.
- Keep straight pipe runs before and after the pressure reducer at least 10×DN to calm turbulence.
- For pressures above 8 bar, inspect the spring every six months; replace only with genuine ITAP parts.
