With PVSI end plate. With PVS end plate max. 300 bar [4351psi]. For 130 l/min contact GMS Product Application Engineering.
In open circuit systems with short P-hoses/tubes, attention should be paid to pressure peaks at flows >100 l/min [26.4 US gal/min].
For system with mid inlet PVPVM. Intermittent pressure at max. 250,000 cycles of full GPV life time cycles, with PVSI end plate.
The maximum intermittent pressure at max. 250,000 cycles stresses the need to confirm application duty cycle before proceeding with specification.
