WARNING

!

To avoid unpredictable system behavior that can cause personal injury
and property damage:

• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.

• Disconnect air supply and depressurize all air lines connected to
this product before installation, servicing, or conversion.

• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.

• Medium must be moisture-free if ambient temperature is below
freezing.

• Service according to procedures listed in these instructions.

• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.

• After installation, servicing, or conversion, air and electrical supplies
(when necessary) should be connected and the product tested for
proper function and leakage. If audible leakage is present, or the
product does not operate properly, do not put into use.

• Warnings and specifications on the product should not be covered
by paint, etc. If masking is not possible, contact your local
representative for replacement labels.

Introduction

Follow these instructions when installing, operating, or servicing
the product.

Application Limits

These products are intended for use in general purpose compressed
air systems only.

Maximum 1034 150 10.3

Installation

E08 and E12 valves should be installed with reasonable accessibility
for service whenever possible. Keep pipe or tubing lengths to a
minimum with inside clean and free of dirt and chips. Pipe joint
compound should be used sparingly and applied only to the male
pipe — never into the female port. Do not use PTFE tape to seal
pipe joints — pieces have a tendency to break off and lodge inside
the unit, possibly causing malfunction. Care should be taken to
avoid undue strain on the valve.

Air applied to the valve must be filtered to realize maximum
component life.

Life Expectancy - Normal multi-million cycle life expectancy of

these valves is based on the use of properly filtered and lubricated
air at room temperature. These valves are also designed to operate
under non-lubricated conditions and will yield millions of
maintenance free cycles.

Factory Pre-Lubrication - Valves are pre-lubricated at

assembly with a petroleum based grease which has a lithium
content.

In-Service Lubrication - In-service lubrication is not required;

however, if lubrication is to be used, use an air line lubricant
(compatible with Nitrile & Polyurethane seals) which will readily
atomize and be of the medium aniline type. Aniline point range
must be between 180° and 220°F. Viscosity at 100°F:
140 - 170 SUS.

CAUTION: Do not use synthetic, reconstituted, or oils with

!

an alcohol content or detergent additive.

CAUTION: Do not restrict the inlet of valves having an

!

internal pilot supply. Pressure supply piping must be the
same size as the inlet port or larger to insure that the pilot
valve receives sufficient pressure supply during high flow
conditions.

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 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.

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.

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

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 Snap­On 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).
