F.A.Q

What is the minimum delivery time for the supply of valves?

The standard delivery time for valves is 10-15 business days. However, in case of emergencies or special situations, we strive to meet the customer's needs by processing the order within 4 days.

To learn more about emergency handling procedures and to obtain information on the earliest available tests, simply send an email (even without text) to: [email protected]. An automatic response will be sent with all the necessary details.

On what types of plant can the valves that you manufacture be installed?

Our safety valves are typically used in a variety of systems, including:

 

Industrial pressure systems

  • Chemical
  • Petrochemical
  • Hydraulic
  • Air compressors

Refrigeration

  • HVAC systems
  • Industrial refrigeration systems
  • Freezer rooms

Cryogenic systems

  • Liquefied gases like nitrogen, oxygen, CO₂

Food and pharmaceutical industries

  • Pressure storage tanks
  • Fluid treatment

Natural gas and LPG systems

  • Stock vessels
  • Gas/ LPG stations

Energy systems

  • Boilers
  • Steam turbines
  • Cogeneration systems

Compatibility depends on the fluid and valve materials. For specific application queries, contact our technical team at [email protected] for dedicated consulting.

What is the definition of the calibration pressure?

The set pressure of a safety valve is the specific pressure at which the valve begins to open and release fluid to protect the system from excessive internal pressure. This pressure is determined during manufacturing or testing and must be:

  1. Compatible with MAWP, the system's maximum working pressure.
  2. Certified according to applicable standards (e.g., PED, ASME, CRN, SELO, EAC).

Essentially, it serves as the "safety threshold" to ensure proper functioning and protection against overpressure in the system.

What parameters are needed to size a safety valve?

 To properly size a safety valve, the following key parameters are required:
  1. Set Pressure: The pressure at which the valve activates.
  2. Type of Fluid: Whether the fluid is gas, liquid, or steam, and its properties (e.g., viscosity, density).
  3. Flow Rate: The amount of fluid to be discharged to protect the system (e.g., kg/h, Nm³/h).
  4. Connection Type: Flanged, threaded, etc.
  5. Fluid Temperature: The temperature of the fluid being discharged.
  6. Required Certification: E.g., PED, ASME, SELO, or other specific standards.

What types of documents do you supply with the safety valve?

With each safety valve, we provide the Declaration of Conformity according to the requested certification, including:

  • CE
  • ASME XIII / ASME VIII DIV.1 UV Stamped
  • TS-SELO
  • CRN
  • UKCA
  • ATEX
  • EAC

Additionally, the User and Maintenance Manual is always included.

On request, additional documentation is available:

  • Technical calculation sheets
  • Material certificate EN 10204 - 3.1
  • Certificate of origin for non-EU destinations
  • Roughness certificates
  • Order compliance certificates
  • EAC passports
  • Special test reports based on customer specifications.

This documentation ensures full transparency and traceability of our supplies.

How often do valves require servicing?

The inspection of safety valves is governed by specific regulations in the country where they are installed. In Italy, the main reference is DM 329/2004, which defines the frequency and procedures for valve inspections. Generally, valves must be periodically inspected to ensure proper functioning and to detect any anomalies, with frequency depending on the type of system and applicable regulations.

Furthermore, inspections must be conducted by authorized bodies or certified professionals, depending on legal requirements.

What payment methods are accepted?

First delivery:
  • Advance Bank Transfer (BB)
  • Cash on delivery

This flexibility ensures compliance with the highest standards required by various markets.

Is it possible to buy adjustable safety valves?

Yes, we offer a range of adjustable overflow valves. These valves allow for the calibration pressure to be adjusted, providing greater flexibility and control based on the specific needs of the system. For more information, please visit our dedicated product page for Overflow Valves!

What maintenance must be carried out to keep the valve in good repair?

To maintain the valve in good condition, regular inspections are crucial, along with avoiding improper installation or maintenance and promptly replacing worn components. Periodic visual inspections are recommended, and maintenance should follow local regulations (e.g., DM 329/2004 in Italy).
