GAS Cartridge - 250 bar
Direct acting - Pressure Compensated
FRS0.G14 Valve Series
Technical Features
External surfaces are oxide burnished and corro-
sion-protected. All valve parts are made of high
strength steel. Spool is hardened and ground to gua-
rantee low wear and to extend service life. Optional:
upon request a calibrated steel wire can be installed
inside the spring chamber in order to prevent possi-
ble orice obstruction (recommended for rated flows
below 2 l/min). Suitable for heavy duty applications.
Extremely compact size. GAS cavity.
NOTE: This product is not intended to be used for
man lifting applications with the purpose to limit the
lowering speed.
A direct acting, screw-in insert type, 2-way pressure
compensated flow control valve. The flow rate of this
valve in the 1 to 2 flow path is largely independent
of the system pressure and is determined by the di-
mension of a calibrated orice. The valve cannot be
adjusted for variable flow output. Free flow in the 2
to 1 path is allowed and not pressure compensated.
