3 INSTALLATION
Valves, as delivered, are ready for installation once valve flange protectors are removed and rust
preventative grease wiped off flange gasket surfaces. A light solvent may be used to fully remove grease
residue.
Install valve in system using proper size and type mating flanges and appropriate gaskets (for RF) or seal
rings (for RTJ). Valve design allows for line flow in either direction.
The pipeline where the valve is to be installed shall be clean, free from sand, welding slags, debris, pieces
of wood and/or any other foreign material that can damage the valve seats during operation.
Actuator and Gear stops are pre-set at the factory and should require no further adjustments. With the
exception of ‘fail-safe closed’ valves, all other valves are shipped in the open position. Valves should not be
closed until the bore of the valve has been cleaned of all debris.
Sizes 6” – 16”
