INSTALLATION / OPERATION / MAINTENANCE MODEL 100-01 Hytrol Valve Description The CIa-VaI Model 100-01 Hytrol Valve is a main valve for CIa-VaI Automatic Control Valves. It is a hydraulically operated, diaphragm-actuated, globe or angle pattern valve. This valve consists of three major components; body, diaphragm assembly, and cover. The diaphragm assembly is the only moving part. The diaphragm assembly uses a diaphragm of nylon fabric bonded with synthetic rubber.
Flow Direction Recommended Tools 1. Three pressure gauges with ranges suitable to the installation to be put at Hytrol inlet, outlet and cover connections. The flow through the 100-01 Hytrol Valve can be in one of two directions. When flow is “up-and-over the seat,” it is in “normal” flow and the valve will fail in the open position. When flow is “overthe seat-and down,” it is in “reverse” flow and the valve will fail in the closed position. There are no permanent flow arrow markings.

Maintenance VALVE STEM THREAD SIZE Preventative Maintenance 1 1/4"—2 1/2" 3"—4" 6"—14" 16" 24" 30” 36” Valve Size The Cla-Val Co. Model 100-01 Hytrol Valve requires no lubrication or packing and a minimum of maintenance. However, a periodic inspection schedule should be established to determine how the operating conditions of the system are affecting the valve. The effect of these actions must be determined by inspection.
Lime Deposits Inspection of Parts One of the easiest ways to remove lime deposits from the valve stem or other metal parts is to dip them in a 5-percent muriatic acid solution just long enough for the deposit to dissolve. This will remove most of the common types of deposits. CAUTlON: USE EXTREME CARE WHEN HANDLING ACID. Rinse parts in water before handling. If the deposit is not removed by acid, then a fine grit (400) wet or dry sandpaper can be used with water.
