• Max. Working Pressure: 31.5 MPa• Max. Flow: 120 L/min• Piston: Seat Area Ratio
Standard: 3:1Decompression type: 20:1
for double check valve
Specifications
• Decompression type is effective in reducing shock when the charged oil compression capacity by the check valve is large.

Characteristics Curve (at 20 mm2/s, 50°C) (typical examples)
■ Pressure Drop Characteristics
Overall valve pressure loss is the sum of pressure losses through each port - P, T, A, and B - as shown in Table 1.Seek values from Fig. 1.
Table 1
▲: Select K, M, N curve according to cracking pressure.
• Pilot pressure required to open the valve (PB1, PA1)To open A line check valvePB1 (B1 line pressure) > (PA + PC – PA1)/fa + PA1
To open B line check valvePA1 (A1 line pressure) > (PB + PC – PB1)/fa + PB1
Where:• PA: A pressure• PB: B pressure• PA1: A1 pressure• PB1: B1 pressure• PC: cracking pressure• fa: surface area ratio
(standard type: fa = 3, decompression type: fa = 20)
