They control the pressure downstream of the valve without requiring pneumatic or electrical control elements. The pressure reducing valve DM 462V is a double-seat diaphragm-controlled and spring-loaded proportional control valve which is predominantly used for hygiene applications in the foodstuffs and pharmaceutical industry. Owing to the PTFE protecting foil the diaphragm is physiologically harmless and can be exposed to steam at a temperature of up to 180°C. The valve is made of stainless steel featuring excellent resistance to corrosion. It has cavity-free internals and is suitable for CIP and SIP. The angled design allows for complete draining. The precise cone spindle guide is arranged outside the throughflow space, thus there is no abrasion in the space through which the medium flows. The design was carried out in accordance with ASME BPE. Clamp connections in accordance with DIN 32676, DIN 11866 line A are standard. The spring cap with spring module and adjusting screw, body bottom (outlet), diaphragm and internals are connected to the body by means of two profile clamps. Thus replacement of the diaphragm or of the entire spring module for another regulating range can be easily done without using special tools. This also applies for maintenance work. Setting the regulating pressure does not change the valve's overall height (non rising adjusting screw). The outlet pressure to be controlled is balanced across the diaphragm 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.
