Spring-loaded pressure reducing valve in 3-part body construction, made entirely of stainless steel paired with sealing materials such as NBR, EPDM, FKM and PTFE-coated membrane materials make this pressure reducer resistant to almost all flow media or environmental influences.
The pressure reducer is available in 3 housing sizes, which enable an exact design to the required pressure flow performance:
- Housing type 01 is designed for a capacity of up to 1,000l/h at a ?p of 1 bar
- Housing type 03 has a max. throughput of 4,000l/h, also at a ? p of 1bar
- Housing type 05 with a flow rate of 7,500l/h, measured at a p of 1 bar
Springs matched to the pressure levels ensure a high repeatability of the set outlet pressures. In the version for gases, a damping element is also used to reduce noise and vibration. The pressure reducers can be recognized by the "-G" in the article number.
Specially developed for the food industry, the pressure reducer impresses with its small dead spaces. All parts that come into contact with media can also be electropolished on request. The spring chamber is separated from the flow chamber by a diaphragm.
The pressure reducer can be sterilized with steam temperatures up to +150°C. The lid can be unscrewed for easy internal cleaning. The O-ring seal in front of the thread ensures that no products can accumulate in the threads.
The compact design enables installation even in confined spaces. The installation position is entirely up to you. The high-gloss surface makes it possible to install it in the operator's direct field of vision, making it easy to use.
Due to the different types of connections available, easy integration into your pipe system is possible, e.g.: thread, clamp or flange connections, welding ends according to DIN 11850-2 or ISO 4200, milk pipe fittings and much more.
How it works The operating pressure flowing off is below the diaphragm and acts as a counterforce to the spring assembly that is mounted and preloaded in the atmospherically ventilated housing. When the pressure force of the outflowing medium exceeds the spring force, the valve seat of the pressure reducer shuts off the flow.
This position is retained as long as there is no withdrawal on the outgoing side. By removing the force below the membrane is reduced and the higher spring force has an opening effect on the valve seat seal.
Setting The pressure reducer is always set without flow movement, so the manometer shows the static pressure.
Increasing the discharge pressure: turn the adjusting screw clockwise
Decreasing the discharge pressure: Turn the adjusting screw counterclockwise. Remove some medium and thereby reduce the pressure. Then tighten the adjustment screw to the desired pressure.
A pressure drop during media extraction is normal, it is due to pressure loss.
Sizing Pressure reducers must be dimensioned according to the expected flow rate (for guideline values, see DVGW worksheet W314). The water flow rate should not exceed 2m/s. In practice, values between 1 and 2m/s are assumed.
For compressed air, the maximum flow rate is 10m/s.
We would be happy to design the right pressure reducer for your application. Please fill out the valve data determination sheet for pressure reducers.
