HSP Regulator - Integrated Pressure Pilot

HSP Regulator - Integrated Pressure Pilot

The HSP Series Main Valve with integral Pressure Pilot reduces steam pressure in steam system piping mains and process applications. This pilot-operated regulator is specifically used in applications where the properties and benefits of Cast Steel are desired and/or specified. Using steel as the material of construction for the main valve body extends the pressure temperature rating of the regulator. A unique two-bolt pilot adapter design and field-reversible tubing offer even greater versatility to this type of regulator, further reducing maintenance downtime.

These valves share the same design and proven reliability of the Watson McDaniel HD-Series Regulators, providing extremely accurate control of downstream system pressure even when inlet pressure to the regulator fluctuates or steam usage varies.

Pressure Pilot

The spring-adjusted Pilot is used for general purpose pressure reducing applications. A Full port strainer and blowdown valve on the pilot adapter allows for ultimate protection against dirt and scale. The innovative design allows the pilot to be mounted on either side of the regulator and is easily field-reversible without having to rebend tubing.

How To Size

From the Capacity chart, find the inlet pressure and required regulator outlet pressure. Follow across chart to  nearest capacity that meets or slightly exceeds demand requirements. Follow vertically up to determine appropriate size. When exact  application values are not shown, interpolate between values.

Example

Application: 1800 lbs/hr of 100 PSIG Steam reduced to 60 PSIG.
Model Code: HSP-14-F150-B ( HSP Full port Valve, 1" 150# Flg, 25-100 PSIG, with no options).

Find the inlet pressure: 100 PSIG 
Next find the required regulator outlet Pressure: 60 PSIG
Follow across to the nearest capacity that meets or slightly exceeds demand requirements: 1800 lbs (2000)
Follow vertically up to determine appropriate size: 2”

Full Capacity Chart

The HSP Pilot-Operated Pressure Regulating Valve is constructed of Cast Carbon Steel for pressure and temperature ratings when compared to ductile iron. The HSP includes pre-mounted Pressure Pilot (similar to PP&PP5 Series) with full port strainer and blowdown Valve on pilot adapter for ultimate protection from dirt and scale. The HSP Pressure Regulator is more accurate than Direct-operated Regulators.

Installation and Maintenance

Pilot Mounting
Standard pilot mounting is on the right side of the regulator when looking into the outlet port. For opposite-mounting, specify when ordering. Pilot mounting on HSP regulators are field-reversible.

Pressure Pilot
The spring-adjusted Pilot is used for general purpose pressure reducing applications.
