4 ASSEMBLY AND INSTALLATION
4.1 INSTALLATION GUIDELINES
The TYPE 3116 and TYPE 3126 threaded gate valves with soft seals can be installed in underground or
surface pipelines both in horizontal or vertical orientation. The listed products are suitable for joining with
threaded ends of pipelines with (thread) size equal to that of the valve threads. Note that the system must not
expose the (gate) valve to bending or tensile stress from loading with the weight of unsupported pipeline sections.
Assemble with consideration to pressure and temperature compensation of the pipeline. The gate valve
assembled and adjusted by the manufacturer is ready for installation. Any dismantling of the valve components
may result in loss of tightness.
4.2 INSTALLATION INSTRUCTIONS
Before attempting to install the fitting, check the technical and commercial documents delivered with the
product to verify that the media and pipeline operating parameters comply with the manufacturer's declarations.
Any change in the operating conditions must be consulted with the fitting's manufacturer beforehand.
Before attempting to assemble the fitting, remove the main bore plugs, check the inner surfaces of the
fitting and thoroughly flush with water, if necessary.
Note! If the product is damaged mechanically, do not install it in the pipeline.
The figure below shows the method for coupling the gate valve and the valve orientation diagrams:
