FLOW DIRECTION: Due to the Trunnion design these valves are capable of handling flow and pressure in either direction.
ALWAYS INSTALL WITH MOUNTING SUPPORTS: The weight of the valve will place undue stress on the connections. This stress can eventually
cause the body or pipe to crack.
THREADED CONNECTIONS: Use PTFE tape or a suitable pipe sealant on threaded connections. Use a strap wrench to tighten up to
1/4 turn more than hand tight. Do not use metal pipe wrenches. Metal pipe wrenches will distort or crack the valve body and
components. Do not attach female threaded plastic valves directly to metal pipe or fittings. Metal pipe should only be used with an
intervening plastic nipple.
SOCKET CONNECTIONS: (PVC and CPVC only). Cut pipe ends square and deburr. Clean mating surfaces with proper solvent.
Apply cement to surfaces and immediately assemble with 1/2 turn rotating motion. Caution: Do this disassembled from valve
to avoid damage. Primer and/or solvent cement/glue used improperly will permanently damage this valve. Do not allow primer
and/or solvent cement to touch any area other than the piping socket. Use of excessive amounts may run, drip, or otherwise enter
sensitive working parts of the valve.
FUSED CONNECTIONS: For Polypropylene Thermal Socket Fusion, follow the fusion equipment manufacturer's instructions. For more
information contact your Plast-O-Matic distributor.
FOR PROPER VALVE PERFORMANCE, IT IS IMPORTANT TO CORRECTLY TIGHTEN THE UNION NUTS: 1.Turn the ball valve to the closed position before
tightening. 2.Tighten the union nuts “hand tight” plus up to one quarter-turn tighter using a strap wrench.
ADJUSTMENTS: If valve is leaking at the PTFE seats or end O-rings simply tighten the union nuts with the valve in closed position.
Use a strap wrench to tighten up to 1/4 turn more than hand tight. Do not use metal pipe wrenches. If leaking continues
then replacement of faulty part is necessary. If leaking occurs at the stem O-ring then replacement is necessary.
DISASSEMBLY OF DOWNSTREAM PIPING: The Trunnion design of this valve enables you to disassemble the down-stream piping
from the valve by unscrewing the valve’s downstream union without leakage from the upstream pressure. To do this,
first close the valve, then slightly loosen the downstream union, then tighten the upstream union and then completely
remove the downstream union. Use extreme caution with dangerous fluids.
VALVE REMOVAL FROM PIPING: The True Union design enables you to simply unscrew the two valve union nuts and slide the valve
body away from the piping. Pressure or liquid head must be removed from both sides of valve before doing this. Use extreme
caution with dangerous fluids.

Final Determination of Suitability of this product for
the use contemplated by the user, the manner of that
use, and safety of that use, is the sole responsibility of
the user.
Proper care must be taken when installing a plastic
valve into a piping system or failure of the valve body
may result
DANGER: DO NOT USE PLASTIC VALVES FOR
COMPRESSED AIR OR GAS
Chlorine Gas (vacuum only): Plastic Valves should
only be used as specified by an engineer or designer
experienced in handling chlorine. Otherwise, DO NOT USE.
NOTE: TO ACHIEVE MAXIMUM CYCLE LIFE, VALVE MUST
BE MOUNTED IN UPRIGHT POSITION
WARNING: THIS VALVE MUST BE INSTALLED IN
CLOSED POSITION.
ALWAYS UTILIZE THE MOST APPROPRIATE PPE DURING INSTALLATION AND SERVICE.
