Tri-grip handknob offered
as a standard control option

highlight_Y Control

Sun Hydraulics offers the Tri-Grip Handknob as a standard control option on select cartridges. The hand knob, configured as the Y Control, is an ergonomically designed knob providing a robust and easy to adjust mechanism that is permanently attached to the cartridge. The knob is constructed of engineered resin, with stainless steel and brass inserts. This offers a completely corrosion-resistant external adjustment knob.

The knob incorporates dual functionality in one package. It can be used as a means for full-range adjustment or as a maximum-setting limiter on pressure controls. If a special setting is specified at time of order, the hand knob will be installed as a maximum setting limiter, and the valve will not be able to adjust higher than the special setting.
