The Series “K” pneumatic control valve meets ANSI B16.15 Class 250, and offers class IV shut-off against the full-rated pressure of the valve, in most cases, without the added expense of positioners, according to the manufacturer. Newly designed 36- or 60- sq in. actuator/yoke assemblies are designed to provide precise control, and are epoxy coated on all stainless steel hardware and internals to guard against corrosion. NEMUR standard mounts are designed to allow easy accessory mounting and simplify installation.
