Medium Pressure Regulators

Regulators for medium pressures up to 16 bar. The ZURCHER-TECHNIK pressure regulators join knowledge, experience and know-how of more than 30 years pressure regulator production and marketing. The high demands and needs by the chemical-pharmaceutical industry have led to develop precise and corrosion resistant pressure regulators.

Reducing Regulator Function  
Medium Pressure Reducing Regulator Operation Reducing Regulator Function Spring-loaded pressure reducing regulators are “relative pressure regulators”, designed to keep the process pressure at a constant level. The nominal pressure is set by means of the setscrew, located at the spring housing. When at rest, the regulator remains in an open position. When the pressure rises, pressure is released through the open valve seat to the process side of the valve underneath the diaphragm. This will continue, until the diaphragm force exceeds the spring force, while the process pressure rises. The diaphragm is lifted and the valve seat closes. In the event that the process pressure drops below the preadjusted nominal pressure, the spring force presses the diaphragm downwards, so that the valve seat opens and admits gas until pressure equalization is reached again.
Back Pressure Regulator Function  
Back Pressure Regulator Function Spring-loaded back pressure valves are “relative pressure regulators”, designed to keep the process pressure at a constant level. The nominal pressure is set by means of the setscrew, located at the spring housing. When at rest, the regulator remains in a closed position. If the process pressure increases, the force underneath the diaphragm increases as well. If the diaphragm force exceeds the spring force, the valve seat opens and the over pressure is discharged to the vent side. If the process pressure drops, the diaphragm force is lower compared to the spring force and the valve seat closes. The pressure in the vent line can be atmospheric or vacuum. With vacuum in the vent line the flow capacity of the regulator is increased.
