Hornung DOM-back-pressure-regulator / DOM-overflow valve VD1 and VDH1
Hornung GmbH launches its new DOM-back-pressure-regulators VD1 and VDH 1.
High-quality pressure regulators for industrial gases and high purity gases,
developed and manufactured in-house, have been representing the company’s diverse
product range for decades. Hornung completes the product range with the new
1″ back pressure regulators VD1 and VDH1 and thus two back pressure regulators /
overflow valves for precise control of low, medium and high pressures.
These products are used in process pressure control and pressure control of pumps
and compressors. The pressure control and constant maintenance of a gas cushion,
for tank superimposition, are also among the applications.
The VD1 and VDH 1 with inlet pressure compensation operate with maximum precision
and reliability. For low and medium pressures (up to 110 bar) the VD1 is available
in brass and stainless steel. The Hornung team designed the VDH1 for high pressures
up to 420 bar. This is also available in brass and stainless steel.
A minimum hysteresis between opening and closing, as well as a flow coefficient of
CV 3. 0 characterize these back pressure regulators. A very high control accuracy is
achieved by a large diaphragm. The sealing materials used allow a temperature range
from -40° C to +150° C, both with EPDM and FKM. An external gas source for the filling
of the dome is not necessary, this offers an extremely user-friendly operability.
Both back pressure regulators are also available with integrated pilot regulator.
This has further increased the ease of operation.
