Code: HSV-A
Description:
Pressure, Vacuum-relief & thermal shock safety valve 3A HSV-A

The valves in the HSV range are hygienic equipment intended to protect tanks against vacuums (vacuum breaker) and/or excess pressure. They are fitted with a technical tube (washing function, sterile air intake). The pressurised function blow-off is collected. The passage sections, different for pressure and vacuum, are specifically designed to protect the tanks against sudden temperature variations resulting from hot washing (and SIP) followed by a cold rinse.
SERVINOX possesses design tools to dimension a valve with respect to tank characteristics (diameter, height), resistance (pressure and vacuum) and washing conditions (temperature, flow-rate).
Key Benefits:
– Valve certified 3-A 58-01
– Combined pressure and vacuum
– Specially designed for protection against thermal shocks (hot/cold washes)
– Fully autonomous (no external control required for its operation)
– Hygienic design
– Simplified and cost-effective maintenance (with no lifting or special tools)
– Numerous options available according to requirements
Technical data: See download document
Applications:

– Tanks not subject to PED compliance where the service pressure is less than 0.5 bar
– Tanks subject to PED compliance where the service pressure is more than 0.5 bar (special version available on option)
– Tanks where the service temperature does not exceed 120 °C
– Exclusively designed to transport gases
