Combination Sequence/PRV Block
Timing and Regulated Pressure in One Unit
Efficient Space Saving Combination Sequence/PRV Block n Control both timing and pressure with this dual purpose combination block. n Common inlet port feeds both sequence and reducing valves.
n 3 (SAE 2) manifold ports: Inlet, Sequenced and Sequenced+Reduced Pressure. n 6 (SAE 4) ports: 2 x Inlet, 2 x Sequenced and 2 Sequenced +Reduced Pressure. n Use with single or double acting devices. n Block includes standard Sequence and PRV cartridges. n Direct acting poppet style valve construction. n Sequence Pressure adjustment range: 750 psi to 5,000 psi, PRV adjustment range: 750 to 4,500 psi. n Enough space is provided on the block to accommodate a Gauge for setup or trouble shooting. n Recommended Filtration: 25 Micron (NOM) / 40 Micron (ABS) (minimum).
