Innovative modular clamping system
Ports 1/4", 3/8", 1/2" NPTF
The Series MC sort start valve is used to
avoid damaging people or equipment when
pressurizing pneumatic systems containing
cylinders.
The features of these components allows one to
pressurize equipment up to 50% of the set outlet
reduced pressure, after which 100% is reached
rapidly.
The usual location of the soft start valve is after
the FRL. The modular design allows for perfect
adaptability with all Series MC.
A pressure switch can be mounted into the
upper part of the unit after removal of the S2610
1/8 plug.
An electrical or pneumatic 3 way Shut-Off valve
may or may not be installed before the unit to
allow Depressurization.
The brass adjustment screw in the head cap
varies the timing constant and the pressure
ramp-up rate.

pressurization time by n° of turns of the regulation screw.
Based on a downstream volume of 5 liters, (.177 FT³)

MC238-AVTF and MC202-AVTF
Constant "K" on the above graphs indicates the number of turns, (open from dead bottom closed), of the regulation screw required
to obtain the required pressurization time with an inlet pressure of 87 psi. Variations of the inlet pressure can cause deviations of
the pressure time by ± 20%.
K = t/V where: V = volume of the downstream system in Liters ; t = desired pressuring time in seconds
Example: V = 5 Liters t = 16 seconds K = 16/5 = 3.2
Using in the graph this value K, the number of turns of the regulation screw will be approx. 1.8 turns open from dead bottom closed.
