2. UNPACKING AND INSPECTION

Carefully unpack the valve and examine the items contained in the carton.

These will include:

• Valve assembly

• User guide

• Fitting and Valve Air Hose

Inspect the unit for any damaged which may have occurred in transit. If such

damage has occurred, notify the carrier at once. Claim for damage must be made

by the consignee to the carrier, and should be reported to the manufacturer.

3. DESCRIPTION

The TS934/TS941 Series Spool Valve is based on a balanced spool design for a

fast “ON/OFF” dispensing action. The hardened spool slides in reinforced

UHMWPE seals and it suitable for use with fluids having a viscosity of 100 to

over 3,000,000 cps, at a pressure up to 2,500 psi (172.4bar). An internal spring

return makes the valve fully adaptable for use with Techcon Systems time/pressure

controllers.

4. THEORY OF OPERATION

The TS934/TS941 Series Spool Valve is normally closed. When air pressure is

applied at air inlet port (1), the spool assembly (2) moves forward to the open

position, allowing the fluid to flow from the fluid inlet port (3) to the fluid outlet

port (4). Relieving the input air pressure allows the return spring (5) to pull the

spool assembly back in the close position, stopping the fluid flow. During the

closing position, the spool movement creates a “suck-back” anti-drip feature.

An Oil chamber (6) is provided, above the upper seal, to create an additional liquid

seal that will prevent moisture from being carried on the spool. The auxiliary air

inlet port (7) is provided so that the valve may be connected for air closing with or

without the spring.
