WRV – WATER REGULATING VALVE (TEMPERATURE CONTROLLED)
Actualizado: 2024-01-05
Construction:The WRV consists of an adjustment part, a valve, and a thermostatic element. The spring housing of the adjustment part is provided with a neutral scale reading from 1 to 5. The valve housing has an internal thread to provide a connection facility for pipes. Sealing of the valve spindle is achieved with the help of rubber diaphragms which, at the same time, ensure that the valve operates almost independent from pressure ratios. The spindle is located in slide bushes with O-rings. These O-rings are located outside the diaphragms and ensure additional safety and sealing. Thanks to the symmetric construction of the valve housing, the valve can operate as either an opening valve (WRV-O) or closing valve (WRV-S). Any change in the operation of WRV-O or WRV-S valves is achieved by turning the valve housing, so that the identification marking \"1/2 DA\" is pointing to the upper part. The thermostatic element consists of a corrugated pipe, capillary tube, and sensor.
Materials for parts coming into contact with water
Valve housing and remaining metal parts Brass (DIN 17660)
Diaphragms ethylene-propylene rubber
Valve cone: nitrile rubber
Valve seat: non-rusting steel (DIN 17440)
Sensor: tinned copper (DIN 1787)
Capillary pipe stuffing box: nitrile rubber
Function
The sensor internal pressure will increase as the temperature rises. This increase in pressure is transferred to the valve cone which then opens to allow the flow. The valves are pressure-relieved in such a way that any change in water pressure will not influence the valve setting. Apart from that, the valves operate independently from the ambient temperature. The universal filling ensures perfect valve operation, irrespective of whether or not the valve housing and corrugated pipe are warmer or colder than the sensor.
CUSTOMIZED HEAT EXCHANGERS
Actualizado: 2024-01-05
SPECIAL REQUIREMENTS REQUIRE EXCEPTIONAL SOLUTIONSCustomized Designs
Universal Hydraulik GmbH is especially known for customized solutions with heat exchangers or cooling systems.
Customized solutions for heat exchangers is the challenge of Universal Hydraulik GmbH, when it comes to variance from the standard catalogue. One option is to use only components of the complete product, e.g. the customer provides the housing of the heat exchanger.
Cooling systems are custom-designed at Universal Hydraulik GmbH.
Examples:
Gas - cooler/heater for BHKW and Fracking
Pre-heating of Bio(Erd)gas protects the gas from condensing. Fully stainless steel cooler.
Slurry (mud water) oil-cooler
Hydraulic cooling for very large brackish water flow Big water tubes 40 mm diameter.
Air Pre-heater
The environmental air is pre-heated by cooled water. The air is on the shell side.
COMPRESSED-AIR COOLER
Actualizado: 2024-01-05
Universal Hydraulik has developed the perfect Heat Exchanger for your water cooled compressor!The hybrid design Heat Exchanger was then further optimized for compressed-air cooling by a \"backpack\"-cooler. This was proven by intensive measurements.
This solution shows the following advantages:
Reduces coolers size by 50%
Reduces air side pressure drop to 1/3
Individual design per compressor size
Compressed-air cooling (water cooled)
Individual design according to customer needs
STAINLESS STEEL HEAT EXCHANGER
Actualizado: 2024-01-05
FOR WATER-WATER APPLICATIONS AND OTHER AGGRESSIVE FLUID MEDIAStainless steel is non-corrosive and can tolerate external influences like lime, water, bacteria and dirt. Due to his low melting point and its stronger expansions after contact with heat, welding stainless steel needs highly-experienced workers with much experience.
High demand meets high quality
Applications within the use of stainless steel often demand stringent hygiene standards and non-corrosive heat exchangers. Universal Hydraulik is attentive towards clean production to deliver highest quality.
BARE TUBE HEAT EXCHANGER
Actualizado: 2024-01-05
DESPITE HYBRID-DESIGN, AN IMPORTANT ALTERNATIVEDepending on the customer’s application, a bare tube shell & tube heat exchanger from Universal Hydraulik is the better choice. High viscosities, or fluids with small particles, may clog the fins used for the hybrid-design.
CKM-bare tube heat exchanger
With the same quality, Universal Hydraulik is manufacturing bare tube heat exchanger for the past several years. We can assist you with the decision if either a space-saving hybrid or a bare tube pipe heat exchanger is the best for your application.
