As pressure is applied to ports A or B it shifts the metal core allowing flow out port C. The SSV-10A Series shuttle is very small and compact, allowing it to be used in the most minute operations. Direct connection to a machine member is made possible by the 10-32 adjustable male threaded output port. The available barb connectors eliminate extra fittings and potential leak points.

In both the flow control and needle valve a finely threaded stem allows gradual adjustment of the amount of controlled flow passing through the valve. Flow enters port 1, travels through an orifice sized by the tapered stem and out port 2. The flow control features a by-pass check whick allows rapid free flow out port 1.

When the button is actuated the stem slides forward and air flow is vented through a non-threaded exhaust port located near the actuator. This valve makes it possible to release pressurized air at a rate of 100 cubic inches in 4 seconds.

Adjustment of the control knob to a pre-determined level shifts the piston, unseating the Buna-N poppet and allowing air to flow through port 1 to port 2. When the set pressure is reached, the pressure under the piston and the force exerted by the spring are balanced producing a regulated output at port 2. A minimum of 30 psi input is required to maintain regulation.

As pressure is applied through input port 1 the poppet shifts forward blocking the exhaust port and allowing flow through output port 2.

In both the flow control and needle valve a finely threaded stem allows gradual adjustment of the amount of controlled flow passing through the valve. Flow enters port 1, travels through an orifice sized by the tapered stem and out port 2. The flow control features a by-pass check which allows rapid free flow out port 1.

Providing fluid handling solutions that meet customer defined performance requirements has been a priority since Pneumadyne's inception, setting us apart in the miniature pneumatics industry.

During actuation flow is directed through port 1 to port 4 as port 2 exhausts to atmosphere through port 3.When released the spool is reversed and the flow is directed through port 1 to 2 as port 4 exhausts to atmosphere through port 5.

When a 3-Way normally closed valve is actuated the stem unseats the poppet allowing flow through port 1 around the poppet and stem and out port 2.

This normally closed 2-Way valve features a stem and poppet that work in conjunction with one another. The poppet seals the exhaust port before it opens to flow. There is no transitional state from one function to the next providing the user precise control between positions.
