Pneumatic Actuators for use with GCV Control Valves PN9000 Series
The PN9000 series actuators are a compact range of linear actuators that are available in 3 diaphragm sizes for matching the requirements of valves at various differential pressures. Each actuator is fitted with a mechanical travel indicator and incorporates a fully-rolling diaphragm, which provides good linearity over the operating stroke.

Logic Unit SRL 6-50
If the level electrode (high or low level limiter) is installed in an isolatable level pot outside the boiler, make sure that the level pot is drained and the connecting lines are rinsed at regular intervals. For this purpose the connecting lines must be shut off and opened at regular intervals and by opening and closing the drain valve the lines and the level pot will be rinsed. The logic unit is designed to be used in conjunction with level switch NRS 1-50 (water level limiter) or level switch NRS 1-51 (high level alarm) to monitor the correct timing and sequence of valve operations. During the rinsing process the level switch jumpers the level electrode, thus preventing the safety or control circuit from opening. The level switch - controlled by the logic unit - also monitors the rinsing and bypass time.

Level electrode NRG 16-11, NRG 17-11, NRG 19-11, NRG 111-11
The water level limiter comprises a level electrode type NRG 1...-11 and a level switch type NRS 1-50. The level electrode NRG 1...-11 consists of two concentrically arranged electrodes (measuring electrode and compensating electrode) which are isolated from each other by special insulating seals.

Steam Trap STERIline® SMK 22, SMK 22-51 suitable for clamp connections to DIN 32676, for pipes to DIN 11866 (DIN 11850, ISO 1127, ASME-BPE) PN 10
The thermostatic steam trap features a minimum stagnant area and corrosion-resistant thermostatic capsule with membrane regulator, which is unaffected by water hammer. Used for removing condensate and air venting steam in sterile and aseptic applications. The thermostatic capsule with membrane regulator and rolling ball features a self-centring ball stud that can move freely, ensuring a steam-tight seal that is unaffected by dirt particles.

819743 Electropneumatic smart positioner SP500
The SP500 smart valve positioner is loop powered from a 4 - 20 mA input signal to provide accurate adaptive positional control of pneumatic actuated linear and quarter turn valves. Precise control is maintained through valve position feedback that automatically varies the pneumatic output pressure to overcome the effects of stem friction and flow forces to maintain desired valve position. Indication of valve position is provided through a continuous digital display of % travel.

Double Swing Check Valve BB 1 BB 2 BB 3
The equipment prevents the backflow of liquids or gases in pipes. The equipment can be installed in horizontal and vertical pipes. If the equipment is mounted in a vertical pipe the flow must normally be from bottom to top. If springs of type 5 VO are used, the equipment can also be installed in vertical pipes with downward flow. This kind of installation (vertically downward flow) is only possible with equipment up to DN 500.
