The pressure reduction occurs by throttling the free cross section between the seat and the cone. Any change in pressure on the downstream pressure side is immediately converted into a lifting movement of the valve cone.
At zero consumption, that is, when the consumption on the downstream pressure side is zero, the valve doesn’t close tightly.
There is no need for additional accessories such as a water seal pot. It is possible to install the valve quick and easy.
They are mainly used in industrial plants, plant engineering and process engineering.
Pressure reducing valves can be supplied with flanges, weld ends or threaded connections.
DN15 to DN200 (1/2“ bis 8“) PN16 to PN40
outlet pressure: 1–40 bar for steam

The pressure reduction occurs by throttling the free cross section between the seat and the cone. Any change in pressure on the downstream pressure side is immediately converted into a lifting movement of the valve cone.
At zero consumption, that is, when the consumption on the downstream pressure side is zero, the valve doesn’t close tightly.
The pressure reducing valve T65 is suitable for compressible media, e.g. compressed air, natural gas, nitrogen, as well as for incompressible media, e.g. water, oil, fuels, LPG (propane, butane) etc.

DN15 to DN65 (1/2“ bis 2 1/2“) PN16 to PN40
outlet pressure: 0,5–20 bar with stainless steel bellow 1.4571 for liquids, gases and steam

The pressure reduction occurs by throttling the free cross section between the seat and cone. Via a pulse line, which is already installed on the valve, the reduced pressure presses on a control piston. As a result, any change in pressure on the downstream pressure side is immediately converted into a lifting movement of the valve cone.
The valve is well suited for intermittent consumption. At zero consumption, that is, when the consumption on the downstream pressure side is zero, the valve closes safely by low pressure increase.
There is no need for additional accessories such as a water seal pot. It is possible to install the valve quick and easy.

Description
Low-pressure reducing and relief valves regulate pressures in mbar range and serve the inertisation and blanketing of containers, reactors, stirrer vessels, centrifuges, etc. with inert gas such as nitrogen.
Inertisation For discontinuous batch processes before process start, the reactor chamber is rendered inert. The inertisation of spaces describes the process to displace the oxygen in the air or other reactive or explosive gases or gas compounds by adding of inert gas

DESCRIPTION Tank blanketing valves are commonly used in tank storage systems to prevent and protect against explosions (avoiding flammable liquids being vented from vessel), to control product contamination against external air that may fill the vapour space, to reduce evaporation losses (consequently product losses), to reduce internal corrosion (caused by air and moisture) and to prevent vacuum condition. The blanketing process consists in covering the stored medium, usually a liquid, with a gas (normally N2). MAIN FEATURES Compact design. No rising stem, except when supplied with top cap.
