# Voltage:
W =24 VDC; Z =100-110/50, 100-130/60 VAC/Hz, e.g., W6577A2902 Z . For other voltages, consult ROSS.
## Voltage: Z=100-110/50, 100-130/60 VAC/Hz.
* Sub-bases and manifold bases ordered separately, refer to page C5.14-C5.18.
** Valve Response Time – Response Time (msec) = M + (F • V). This is the average time required to fill a volume V (cubic inches) to 90% of supply
pressure or to exhaust it to 10% of supply pressure. M and F values are shown above.
