Balancing valve MCACA series

cartridgethreaded

Specifications · Operating Pressure:280BAR · Flow:60L/min · Internal Leakage:0.3ml/min.max.to 85% of norminal setting · Pliot Ratio:3:1 · Temperature:-40°C to +120°(-40°F to+250°F) · Cavity:T-11A · Fluids:Mineral-based fluids with viscosities of 7.4 to 420 cSt. Features · The setting value of the balance valve should be at least 1.3 times of the load pressure value. · Three-port vented Valve is atmospherically referenced and considered problem solvers for existing circuits using non-vented Valve. Over time, the vented Valve may leak externally or allow moisture into the spring chamber. Four-port vented counterbalance Valve are recommended for new applications · Reseat exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reseat percentages Operation Atmospherically vented counterbalance Valve with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot- assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. Backpressure at port 2 does not affect the valve setting because the spring chamber is atmospherically referenced.
