The Altecnic / Caleffi 311 Safety Valve - 311430 is essential for domestic hot water systems, safeguarding the hot water cylinder and boiler, as well as other components within heating systems. This reliable valve is meticulously chosen based on the required set pressure. When the pressure exceeds the designated limit, the valve activates, discharging excess pressure to the atmosphere. This crucial function prevents the pressure within the system from escalating to hazardous levels, ensuring the safety of the boiler, hot water storage cylinder, and surrounding personnel.

Specifications

• Size: 1/2" x 1/2"
• Connections: BSP Female Inlet x BSP Female Outlet
• Materials: Brass
• Medium: Air and Water
• Set Pressure: 3 Barg
• Discharge Flow Rate: 142.1 kg/hr
• Max Boiler Rating: 82.5 kW
• Temperature Range: +5 to +110°C
• Product Code: 311430
• Notes: WRAS approved, CE marked

Ensure the safety and efficiency of your heating system with the Altecnic / Caleffi 311 Safety Valve, a trusted solution for managing pressure and safeguarding your equipment.

The FSY90S Sanitary Rupture Disc is a compression-loaded, reverse-acting disc with precision scoring around its circumference, engineered to meet the stringent hygiene standards of 3-A SSI for public health protection. Designed for use in the pharmaceutical, food, and biotechnology sectors, it is manufactured as standard from AISI 316L stainless steel, with alternative alloys available on request.

A smooth process-side surface makes the disc ideal for CIP and SIP cleaning processes, helping maintain aseptic conditions. Installation is simplified using PTFE gaskets certified to FDA, USP Class VI, 3-A, and EU 10/2011 standards, enabling secure fitment in sanitary clamp connections such as Tri-Clamp and Tank Connection fittings.

The FSY90S is suitable for use with gases or liquids (with a gas cushion) and performs reliably under cycling and pulsating conditions without compromising safety. On reversal, the disc opens fully within milliseconds along the scored line, ensuring clean, fragment-free rupture and dependable pressure relief.
