A pressure regulator without auxiliary power, suitable for a temperature range from -10 to 80ºC

industrial valve

At Valfonta we have an extensive catalogue of pressure reducing valves designed to cover the widest possible range of applications in the industrial, chemical, and pharmaceutical sectors.

In this post we would like to talk about an industrial valve for gas – nitrogen, air and others–, liquids and steam. The M2 model is one of the most common, used and demanded models in all types of systems and installations within the industry and the current market.

Let’s start by looking at its applications. It is commonly installed in chemical laboratories, water distribution networks, sanitation installations, compressed air industrial installations, fire extinguishing systems, for inert gas control, protecting the product in the tank from oxidation, etc.

We have also installed it in special systems and constructions; these are steam systems operating at a temperature of up to 180ºC, and this is possible thanks to its technical characteristics, the most important of which are highlighted below:

  • Various gasket compositions for food applications

  • Stainless steel actuator

  • AISI316 PTFE interior seals

  • Interior compensation socket

It works with a pressure range between 0.02 and 8 barg, with several different actuators. It has a diaphragm with an intermediate reinforcement fabric.

As far as the condensation tank is concerned, it is supplied and required when the fluid is steam or for liquids with a temperature above 125ºC, in order to protect the diaphragm from overheating.

It is important to bear in mind that this model is not a safety valve and, where necessary, overpressure protection must be installed

How our M2 valves work: direct action principle

“VALFONTA M2” pressure reducing valves work according to the direct action principle. This means that the upstream pressure reaches the valve and pushes the shaft-piston-plunger ensemble to close automatically.

When the adjustment screw is then turned clockwise, this causes the spring to move so that it activates the diaphragm and closes it, opening the valve until it reaches the required downstream pressure.

Any upstream pressure variations will be absorbed by the compensating plunger and the downstream pressure will be absorbed by the diaphragm.

As far as the installation process is concerned, mounting on horizontal pipes would be preferred, with the actuator at the top.

For steam installations, on the other hand, the actuator must be installed at the bottom and must be accompanied – if the temperature exceeds 125ºC – by a barrel filled with water to protect the diaphragm.

A filter must be installed at the valve inlet to avoid over maintenance of the balancing pipe. The distance between the valve and the pressure tapping point should be approximately 6 x DN.
