The TN2000 series pneumatic piston actuators are designed for use with DN125 to DN300 Spira-trolTM control valves. There are three versions available: Single-acting, Double-acting (spring assist) and Double-acting (no springs) for matching the requirements of valves at various differential pressures and in a variety of applications.
O posicionador eletropneumático EP6 pode controlar qualquer válvula que seja acionada por um atuador pneumático linear em conformidade com a norma NAMUR. Ele garante uma proporcionalidade exata entre o curso da válvula e o valor do sinal elétrico de entrada (mA) no posicionador.

Le positionneur numérique SP400 contrôle la position du clapet de toutes vannes pneumatiques à déplacement linéaire ou rotatif en fonction d'un signal de commande 4-20 mA.
The EP6 Electro-pneumatic positioner can control any valve that is actuated by a linear pneumatic actuator that conforms with NAMUR. It guarantees an exact proportionality between the stroke of the valve and the value of the electrical input signal (mA) into the positioner.
Le positionneur numérique SP7-1* peut contrôler n'importe quelle vanne actionnée par un actionneur pneumatique linéaire ou rotatif conforme à NAMUR.
The EP5 is a 2 wire loop powered positioner requiring a 4-20 mA control signal, and is designed for use with linear pneumatic valve actuators. The positioner compares the electrical signal from a controller with the actual valve position and varies a pneumatic output signal to the actuator accordingly.
De reeks pneumatische servomotoren BVA300 gebruikt een duebbele tandheugel en rondsel die een lineaire beweging omzet in een kwartslag.
Les régulateurs pneumatiques Séries 4000 sont munis de deux plaques avec vis de fi xation et d'un support pour l’installation sur panneau ou au mur.
