Self-acting pressure reducing valves are simple control valves offering accurate control while being easy to install and maintain. They control the pressure downstream of the valve without requiring pneumatic or electrical control elements.
The pressure reducing valve DM 152V is a sanitary diaphragm-controlled, springloaded proportional valve that is primarily used for hygienic applications in the food processing and pharmaceutical industries. The diaphragm is made of EPDM which renders it steamproof up to 180 °C. The valve cone is fitted with a soft seal. No external sense line is required.
The valve is made of stainless steel 1.4404 / 1.4435. It meets ASME BPE design requirements and can be used in CIP and SIP systems. The angled design allows complete draining while the valve is open.
The bonnet with spring module, adjusting screw, diaphragm and internal parts as well as the inlet connection are attached to the body by solid clamps, each with two screws. Changing the diaphragm or the complete spring assembly for a different control pressure range is extremely simple and does not call for special tools. The same applies to changing the cone seal in the event of maintenance.
Adjusting the set pressure does not change the overall height of the valve (non-rising adjusting screw). The outlet pressure to be controlled is balanced across the control unit by the force of the valve spring (set pressure). As the outlet pressure rises above the pressure set using the adjusting screw, the valve cone moves towards the seat and the volume of medium is reduced. As the outlet pressure drops, the valve control orifice increases; when the pipeline is depressurised, the valve is open. Rotating the adjusting screw clockwise increases the outlet pressure.
These valves are no shut-off elements ensuring a tight closing of the valve. In accordance with DIN EN 60534-4 and/or ANSI FCI 70-2 they may feature a leakage rate in closed position in compliance with the leakage classes V.
Features & Benefits:
Not sure if this is the right product? Pressure Reducing Valves are designed to reduce a high and frequently fluctuating pressure to an adjustable constant pressure downstream of the valve. A spring keeps the valve open and this closes as the outlet pressure rises. These self-acting pressure reducing valves are used to protect all the devices, valves and installations situated downstream from any excessive pressure build-up. Simultaneously the consumption is reduced and the flow velocity and noise are minimised. A spring keeps the valve open and the outlet pressure moves through the control element (diaphragm, piston or bellows) onto the cone, and in the event of rising outlet pressure, proportionally closes the valve. The outlet pressure to be controlled can be adjusted by a pre-tensioned/relieved spring via an external adjusting screw.
