Stauff Valves | Hydraulic Ball Valves
Increased Corrosion Resistance Offered on Stauff Valve.
To meet the demands of our customers, who are requiring increased corrosion resistance in hydraulic components, Stauff improved corrosion-resistant zinc-nickel surface coating for their most popular high-pressure ball valves. This upgrade to zinc-nickel coating greatly increases the number of STAUFF products supplied with a standardized, high-quality surface coating which has¬ been proven in a variety of applications. The zinc-nickel surface is chrome 6 free and offers over 1,200 hours of resistance to red rust corrosion in salt spray chamber testing. It has a high-quality appearance similar to stainless steel and meets all relevant ELV, REACH and RoHS requirements.
Hydraulic Ball Valves
Ball valves comprise of a valve body with a straight-line passageway connecting the inlet and the outlet ports. The valve instrument is a spherical piece attached to a shaft. The ball contains a precision-machined hole that is the same size as the passageway through the valve body.
When the valve parts are assembled, the shaft holds the hole through the ball in alignment with the passageway through the valve body.
An operator is able to rotate the ball by either a handwheel or other type of handle on the shaft. When the ball is turned ¼ of a turn (equal to 90°), the valve is turned from a fully open position to a fully closed position.
When the valve is in the fully open position, there is an unrestricted movement of hydraulic fluid through the valve.
