The possible volume of flow through the valve depends on the used pneumatic hoses. The table shows the flow rate according to the used pneumatic hose (reference pressure 6 bar). In order to alleviate the choice of the SDV-P, SCHUNK has defined a recommended hose diameter. This is relevant for the allocation suggested by SCHUNK.
In general, possible additional combinations can be determined as follows:
1. Calculation of the required flow rate for the variant of the components:
required flow rate Q [l/min]
Fluid consumption per double stroke V [cm3]
Closing or opening time t [s]
Q = 0.21*(V/t)
2. Selection of the right SDV-P: the flow rate of the SDV-P must be larger or equal to the calculated required flow rate Q. If this is not taken into consideration, the cycle time may increase.

General notes about the series

Rate of flow
For the SDV-P and SDV-P-E variants, the possible volume of flow through the valve depends on the used pneumatic hoses. The table shows the flow rate according to the used pneumatic hose (reference pressure 6 bar). The diameter refers to the outer diameter of the hose. The relevant inner diameter can be slightly different depending on the manufacturer and minimally affect the values. The SDV-P-E-P variant does not have hose-dependent flow rates

Valve switching time
purely the switching time of the SDV-P valve without other loads. Valve switching times must be added to the movement times on the load side, such as the opening and closing times of the respective gripper.

Pressure loss, input/output
Describes the pressure loss between input and output pressure through the spring-actuated check valves. This pressure loss may have to be taken into account when the connected actuators are configured.

Manual quick ventilation
The SDV-P-E and SDV-P-E-P variants are equipped with manual quick-release ventilation. They allow venting the connected actuators without having to remove the pneumatic hoses (for example, During set-up or before restarting the system after an emergency stop).

Housing material
Aluminum

Actuation
pneumatic, with filtered compressed air as per ISO 8573-1:2010 [7:4:4].

Warranty
24 months
