Yoke Clamps

GLS Series

The GLS Series control valve actuator is attached to the valve body by means of two yoke clamps, manufactured with investment cast stainless steel. Each clamp has a flat-sloped surface, so when one clamp is bolted to the other, a force is generated, securing the actuator yoke firmly to the valve bonnet. This is in contrast, to threaded clamps, used on conventional control valves. The design of Valtek Sulamericana’s GLS control valve clamps allow for easy removal, even under severe corrosion conditions. For valves with larger sizes or higher pressure classes, the actuator yoke is bolted directly to the valve bonnet.


GLH Series

The actuator on the GLH Series control valve that is used for high pressure applications is attached to the valve by means of bolting that secures the actuator yoke to the valve bonnet. For smaller sizes, the actuator yoke is connected to the valve bonnet by means of two yoke clamps that are manufactured in investment cast stainless steel. Similar to the clamps used on the GLS control valve, each clamp has a flat sloped surface, so when one clamp is bolted to the other, a force is generated, securing the actuator yoke firmly to the valve bonnet. In contrast to conventional threaded clamps, the design of GLH clamps allows their easy removal, even under severe corrosive conditions.
