E08 and E12 Slow-Start / Quick Dump Valve 83-964-000

Function

The Slow-Start / Quick Dump valve is a 3-Port valve which supplies

air in a controlled reliable manner to pneumatic systems and has

the quick exhaust features of a dump valve. This valve replaces

conventional main valves.

The Slow-Start / Quick Dump valve operates much like a standard

3-Way valve. When the valve is installed Port 2 is connected to

Port 3 (downstream system is exhausted to atmosphere). When a

signal (pneumatic or electric depending upon pilot operator) is

received in Port 12, the connection between Port 2 and 3 is closed.

At the same time, supply air from Port 1 is connected to Port 2

through the adjustable throttle (Flow Control Screw). When the

downstream pressure reaches a specific point, the main poppet

opens and permits full air flow through the valve. The table shows

the relationship between the inlet pressure and the downstream

pressure at which the main valve opens.

When the pilot signal is removed, the valve returns to its

initial position and the downstream air is dumped rapidly through

Por t 3.

Installation

The Slow-Start / Quick Dump valve

replaces an ordinary main valve;

therefore, it is usually mounted

between the air preparation unit

and the system. The Slow-Start /

Quick Dump valve is specifically

designed to mount directly in line

with the Series using modular

body connectors.

Port Connections

1. Connect inlet air supply to Port 1.

2. Connect mufflers (or plumb exhaust) from Port 3.

3. Connect cylinder Port 2 to cylinder or other system devices to be

supplied air.

4. Signal Connection – Slow-Start / Quick Dump valves may be

remotely controlled electrically or pneumatically.

a. For solenoid pilot operated valves, see the instructions under

“WIRING INSTRUCTIONS.”

b. For air pilot operated valves, connect the air line to the pilot

port 12, (M5 or 4mm tube).

Wiring Instructions

CAUTION: An interruption of 10 milliseconds or greater to

the power supplied to the solenoid of a solenoid operated

valve may cause the valve to shift. Provision must be

made to prevent power interruption of this duration to

avoid unintended, potentially hazardous, consequences.

NOTE: In addition to the following instructions, follow all requirements

for local and national electrical codes.

Attach an electrical cable with connector (that conforms to the DIN

43650, Form C pattern) to the terminals of the solenoid. For

locations in a cabinet or other protected environment, the Snap-

On connector with loose wires may be attached. In both cases,

do not attach or remove the connectors until power is off.

Electrical Connection

Valves with 3-Pin male terminals should have power connected to

the parallel terminals. Ground should be connected to the

perpendicular terminal. Use only connectors that comply with DIN

43650, Form C (8mm blade spacing).

Override Operation

The flush non-locking manual override is located on the body of

the solenoid pilot. To operate the override, place a small screwdriver

in the slot of the override and turn approximately 45° in either

direction until the solenoid pilot actuates. The solenoid pilot will

remain actuated until the override is released. When released,

the solenoid pilot de-actuates.

Solenoid Replacement

To replace the solenoid, remove the two mounting screws and replace

with the correct voltage solenoid. Tighten new screws 5 to 6 in.lbs.
