CAUTION:
When ordered, the weight operated valve conguration
and construction materials were selected to meet
specic pressure, temperature, pressure drop and uid
conditions. Some elastomer and trim material may allow
for higher or lower temperatures and pressures.
Do not subject the valve to any other conditions. This
information can be found in the technical specications
document at Kimray.com. For assistance in determining
what your valve is capable of, contact your local Kimray
store or authorized distributor.
NOTE:
The MAWP for this valve is lower than the connection
type, ANSI class 150.
CAUTION:
The instructions provided herein should be completely
reviewed and understood before operating or repairing
this equipment. All CAUTION and WARNING notes
must be strictly observed to prevent personal injury or
equipment damage.
Do not install, operate, or maintain this valve without
being fully trained and qualied. If you have any
questions about this manual, contact the Kimray
applications support team before proceeding.
A1 Scope
This document contains information for Kimray weight
operated dump valves and includes detailed installation,
operation, and repair/maintenance information for the
product.
A2 Description
The Kimray weight operated valve is a zero-emissions
product designed as an oil or water valve for emulsion
treaters, water knockouts, salt water disposal and
gun barrels. The valve is balanced by equalizing gas
pressure directly from the vessel and actuates based
on the hydrostatic pressure generated from the column
of liquid in the vessel’s discharge piping. The height of
water column can be eld adjusted by moving the weight
in or out on the arm and ranges from 2 ft to 4 feet, with
options up to 12 feet.

Before installing the weight operated valve, inspect it for
shipment damage and for foreign material that may have
collected during shipment. Check tightness of fasteners
prior to valve installation. Fasteners have the potential
to loosen in transit. This is recommended to ensure your
safety and proper valve function.

1. For anged bodies, remove the masking sticker from
the raised face of each end connection & use a
suitable gasket between the body and the pipeline
anges.. For threaded (NPT) bodies, use TFE tape
or pipe thread sealant on external pipe threads.
2. Install valve with the arrow on the body pointing
towards the direction of ow. The direction of ow
indicated will not necessarily prevent ow in the
opposite direction.
3. Install Drip Pot and ensure the drain valve is closed
tightly.
4. Install gas equalizing line to 1/4” connection of Drip
Pot. The equalizing line must be horizontal or
sloping downward towards the drip pot so that any
condensate liquids will accumulate in the drip pot.
Any dips or low spots in the equalizing line could
allow liquid to accumulate and freeze, blocking ow
of equalizing gas, causing an imbalance.
NOTE:
DO NOT connect equalizing line with any other devices
that could consume or vent gas. This would create an
imbalance between the equalizing port and upstream
liquid pressure
5. Adjust weight on Lever Arm for desired water column
height. See gure 1-2 for adjustment heights.
6. Pressurize the system and check operation.
CAUTION:
Verify all pressure connections are tight before
pressurizing the system.
NOTE:
To prevent injury, Never stand directly over or in front of a
valve when the system is pressurized.

Kimray recommends using the special tools below for
disassembly and re-assembly.

The drain valve at the bottom of the drip pot should
be opened regularly to drain any accumulated liquids.
Frequency will be dependent on application and ambient
conditions. Start by draining daily and then extend inter-
val if warranted. Ensure drain valve is closed/tightened
after draining.
We recommend that the wearable components be
replaced and critical components be inspected at an
initial interval of 12 months. This interval may increase or
decrease depending on application conditions. Wear-
able components are all included in Kimray Repair Kits.
To order, contact your local Kimray store or authorized
distributor.
The valve can be repaired without being removed from
the piping.
CAUTION: Block and bleed all pressure from the valve
prior to performing any maintenance
