2450 Rate Of Flow Control Pilot
The Model 2450 is a two-way, normally open pilot that senses the differential pressure across an orifice plate; high pressure under its diaphragm and low pressure above the diaphragm. The orifice plate differential is proportional to the flow rate through it. The pilot balances the differential against an adjustable spring load. An increase in differential, hence rate of flow, above the spring set point tends to make the pilot close.
The Model 2450 is the standard pilot for OCV Series 120 Rate of Flow Control Valve. Sensing the differential across the valve’s integral orifice plate, the pilot modulates the main valve to regulate or limit the required rate of flow.
- Normally Open, increasing differential closes
- Simple Adjustment
- Large diaphragm area for sensing small changes in differential pressure
- Dual chamber, hydraulically balanced for accurate control
- Bronze or stainless steel construction
- All parts replaceable while mounted on valve
