The PV-ECO is designed for use on Chemical Carriers and Product Carriers addressing the special requirements for P/V valves installed on long pipes. The PV-ECO offers:
Pres-Vac is ISO 9001 certified to ensure consistency of the high-quality products that Pres-Vac is known for.
Compliance with rules and regulations
Flashback testing at low flow rates following EN ISO 16852:2016. The flashback tests shall be performed on pipe lengths equal to or longer than the pipe length, on which the valves are to be installed. This is mandatory according to EN ISO 16852:2016.
Effective relief of tank pressure
The PV-ECO valve provides effective control and management of the tank pressure. If the pressure exceeds the specified opening pressure, the valve will open immediately and relieve the excess pressure. Similarly, if pressure during discharging gets below the specified opening pressure, the valve will open and relieve the vacuum. The PV-ECO valve has an advanced flow control design to manage tank pressure:
High closing pressure
The patented new flow control system secures that the PV-ECO valve has a very high closing pressure reducing blowdown to 5-6 kPa. This means substantial reductions in loss of inert gas and cargo vapour compared to other P/V valves.
Low noise level
The PV-ECO valve is designed to minimize noise during operations. By optimizing the nozzle design, the noise level of the PV-ECO valve has been reduced by 10-15 dB compared to other designs. In many applications, hearing protection will not be required.
The PV-ECO valve has been made easier to maintain by the following features:
Configured to your requirement
Pres-Vac P/V valves are individually configured to suit your specific requirements:
Operations and maintenance made simple
The PV-ECO valve has been designed to simplify operation and maintenance. Daily operations by the crew are made simple by the following features:
The PV-ECO valve is always configured to meet the specific requirement of every single customer. Different vessel designs need different venting requirements for pressure and vacuum valves. Furthermore, vessel designs tend to use different piping arrangement and consequently require different flange sizes and flange standards.
The pressure side of the valve can be delivered in four different sizes and the vacuum side can be delivered in three different sizes. The pressure and vacuum sides can be freely combined to deliver the combination most suitable for your vessel. All the combinations can be delivered in different flange sizes and with all flange standards.
Furthermore, Pres-Vac offers a broad range of options for the PV-ECO valve:
Custom solutions and special requirements can be delivered upon request.
Option: Integrated gas freeing cover
The design is made in a way that the cover releases the maximum amount of vapour that the size of the piping allows.
Option: Compliance with OCIMF, 10% requirement
Option: Electric, steam or thermal heating
*Ice accretion occurs when waves or heavy rain is present with surface temperatures at or below freezing. A layer of ice will accumulate and prevent the valve from functioning properly.
Option: Custom coating
Option: High-pressure dual valve
The PV-ECO valve is available in two different versions:
You should choose a PV-ECO Ultimate if you are particularly concerned about leakage protection, loss of inert gas, disc/seat and flame screen maintenance costs.
The PV-ECO Ultimate delivers all the features of the PV-ECO Superior and three additional safety and maintenance features:
You should choose the PV-ECO Superior if your focus is to get a safe and very reliable P/V valve of high quality.
Maximum safety for crew, vessel and cargo
Compliance with all current and foreseen regulations
Designed to your needs
Excellent operational performance
Low maintenance costs
