TRAC STYLE 'R' STEAM PRESSURE REDUCING VALVE

The TRAC Style ‘R’ steam pressure reducing valve is an internal pilot and internally ported valve utilized for regulating and reducing high pressure steam to any desired operating pressure within its adjustable range. The Style ‘R’ valve requires no external source of power to operate the valve or to detect changes in outlet steam pressure.

The Style ‘R’ valve is intended for installation in low pressure steam systems such as, preheaters, laundry equipment, and galley equipment. The inlet pressure rating of the Style ‘R’ valve is 150 psig and the outlet set pressure is adjustable from 15 to 135 psig. The valve requires at least a 15 psi pressure difference between steam supply pressure and maximum regulated pressure. It can be adjusted to limit maximum output pressure to any value from 15 psi below supply pressure down to 5 psi gauge pressure.

FEATURES
Fully Guided Main Valve - The hardened 440C stainless steel main valve and stainless steel guide prevents galling or binding of internal parts for smooth operation.
Renewable, Interchangeable Parts - The reducing valve can be completely overhauled without removing valve body from the line. Internal trim is fully replaceable, without the need for secondary machining operations.
Stainless Internal Parts - The stainless steel valve seat ring with stellite seat face resists wire drawing. The main valve and cylinder liner are machined from hardened 440C stainless steel. Internal springs and diaphragm are corrosion and heat resistant inconel.
Packless - There is no external stem or other control mechanism penetrating the pressure envelope, and no stuffing box or packing is incorporated in the valve design.
Sensitive Diaphragm - Responds instantly to any flow change and eliminates stuffing boxes and bellows seals. Full travel less than its own thickness minimizes stress on the diaphragm.
Accurate Regulation - Comparable to instrument control with full flow for equivalent pipe size.

The TRAC Style ‘R’ pressure reducing valve is manufactured in accordance with the general requirements of the following military specifications (Departures from the military specification valve are available- these modifications include but are not limited to changes in body material, trim material, end connections, and rated pressure):
