5. Installation angle
Install the product so that the arrow mark on the valve
body points horizontally in the direction of steam flow, and
it should be installed horizontally in the piping with the
actuator at the top. Allowable inclination is 10 degrees in
the fore-aft direction and 15 degrees in the plane
perpendicular to the steam flow line.
6. Piping support
Install the product, paying attention to avoid excessive
load, bending and vibration. Support the inlet and outlet pipes securely.

8. Drainage port usage example
The threaded condensate drainage port at the
bottom of the body makes possible installation of a
blow valve or steam/air trap. Because the
condensate drainage port is located on the primary
side of the product, condensate flowing in the
primary side piping can quickly be eliminated,
contributing to prevention of valve seat erosion and
rapid start-up of the equipment.
If there is a problem in operation, determine the cause
using the “Troubleshooting” section in this manual.
