NY Series Linear Pneumatic Actuators

The NY series linear pneumatic actuators represents a broad range of field proven, it suitable for automating most types of rising stem valves in safety shutdown and control applications. The NY actuators are manufactured in accordance with strict quality standards and assure reliability and safety in your specific service. This catalog lists standard models intended to cover a wide range of sizin

NY Series Actuators

NY Series scotch yoke actuator is designed for the general purpose of valves and damper automation and offer a wide range of torque to operate ball, butterfly, plug valves, dampers or any device that requires a quarter turn operation for on-off or modulating service.NYS series actuators are designed with SYMMETRICAL yoke, so at 0 and 90 degree position of the stroke

NSV Solenoid Valve

NSV Series solenoid valves include body-ported and NAMUR two kind of connection type. And there are two options for material of solenoid valves to choose: anodized aluminium or AISI316.Each solenoid valve is field interchangeable for use on either double acting (5-way) or spring return (3-way) actuators and is available in single coil, dual coil, or 3-position configuration (open centers, closed

NST Series Actuators-TYPE

COMPACT DESIGN: The NSEC rack & pinion stainless steel pneumatic actuator provides linear torque output in a compact design utilizing the same body and end caps for double acting and spring return units.AISI 316: all external components (body, end caps, pinion and fasteners) are made in stainless steel (CF8M or AISI 316) for a superior corrosion resistance.

NL35-55 Limit Switch-NSEC

NL35 is a very compact limit switch box, thereby allowing maintenance of a smaller valve envelope size.NL35 comes standard with a high visibility beacon, offering clear location of the current valve position.The operating position of the switches can be easily changed by adjusting the high resolution spline cams manually and independently without the need for additional tools.

NEV Series Solenoid Valves

BNF Series

Resilient-seated butterfly valves have widen their range of applications due to their reliability and advantages compared to traditional ball and globe valves. In particular, the NSEC BNF series are used in different industries both for ON-OFF and flow control service of any type of fluid.

NT Series Actuators-TYPE

The NSEC rack & pinion pneumatic actuator produces linear torque output in a compact designutilizing the same body and end caps for double acting and spring return units. Namur VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required tomount solenoid valves, limit switches or positioners.The standard angle of rotation is 90°. Additional travel rotations of 120°, 135
