Do not mount the valve with the stem pointed lower than horizontal.. Mount the valve with the flow arrow pointed in the direction of flow through the valve.. Mount the valve between aligned pipes. Mounting the valve on pipes that are not aligned causes leakage at the valve to pipe connection.. Ensure complete engagement on pipe to valve body threads. 6. Hold the valve body with a clamp or pipe wrench on the hexagonal fitting nearest the pipe to prevent damage to the valve body while mounting on the pipe. Refer to Fig... e sure to allow enough room for installation and service. Clearance for valve installation is dependent on the actuator size and valve pipe size.

VN THREE-WY THREDED GOE VVE CHECKOT se the following procedure to check for proper valve operation:. Check the valve body and connections for leaks. IMPORTNT efore installing linkage and actuator, make sure that the valve stem operates freely. Impaired stem operation can indicate that the body was twisted or the stem was bent. Either of these conditions can require valve replacement.. fter installing linkage and actuator, check the operation according to the installation information furnished with these controls.. Operate the system through one complete cycle to ensure the valve controls properly.. Check the valve at regular intervals for leakage around the packing. NOTE: The packing is spring-loaded and should seldom require attention.. If leakage is discovered and inspection shows that the packing gland is screwed down tightly, then repack the valve. utomation and Control Solutions Honeywell International Honeywell Europe S..
