GENERAL INSTRUCTIONS
Valtek
®
Tek-Check is a high performance piston check
valve featuring piston and non-slam piston designs.
Many features have been incorporated into the design to
maintain maximum interchangeability with other
Flowserve
TM
valves.
The following instructions are designed to assist in
unpacking, installing and preforming maintenance as
required on Tek-Check valves. Product users and main-
tenance personnel should thoroughly review this bulle-
tin prior to performing any maintenance on the valve.
To avoid possible injury to personnel or damage
to valve parts, WARNING and CAUTION notes
must be strictly adhered to. Modifying this prod-
uct, substituting nonfactory parts, or inferior
parts, or using maintenance procedures other
than outlined could drastically affect per-
formance and be hazardous to personnel and
equipment.
Unpacking
1. While unpacking the valve, check the packing list
against materials received. Lists describing valve
and accessories are in each shipping container.
2. When lifting the valve from shipping container, posi-
tion the lifting straps through the yoke legs to avoid
damage to the tubing and mounted accessories.
WARNING: When lifting an actuator with lifting
straps through the yoke legs, be aware that the
center of gravity may be above the lifting point.
Therefore, support must be given to prevent the
actuator from rotating. Failure to do so can
cause serious injury to personnel, damage to
the valve or nearby equipment.
3. Contact your shipper immediately if there is shipping
damage.
4. Should any problem arise, call your representative.
Installation
1. Before installing valve, clean the line of dirt, scale,
welding chips, and other foreign material.
2. Valtek Tek-Check valves are designed to open with
as little as five psi (0.34 Bar) pressure difference
across the valve. Smaller sized non-slam piston
check valves (4-inch and smaller) can be mounted
in vertical lines with the addition of a spring posi-
tioned behind the piston.
3. Double-check flow direction to be sure valve is
installed correctly. Flow direction is shown by the
arrow attached to the body flange. If flow arrow is not
attached, refer to Figure 1 or 2 for proper flow
direction.
CAUTION: Valve will not operated if installed
incorrectly.
