| The Types FR, FR-6 and FR-10 are fully automatic back pressure valves designed to dependably maintain a desired pressure in a vessel or system by maintaining a predetermined valve inlet pressure and relieving excess pressure into a lower pressure line. FR Series vakres are not emergency relief devices, but am designed for continuous pressure regulation. May be used in centrifugal regenerative turbine, reciprocating or rotary pump bypass valve application. | Most fluids and gases except steam, all grades of oils, including Bunker "C". | TecSheet FR, FR-6, FR-10 | $List Prices |
| The Types FRM, FRM-C and FRMQ function as automatic pressure limiting regulators, maintaining a desired pressure in a vessel or system by maintaining a predetermined valve inlet pressure and relieving excess pressure Into a lower pressure line. These valves are small and compact yet are highly efficient making them suitable for numerous applications that call for small, accurate back pressure regulator. Types FRM and FRM-2 incorporate the same superior "floating ring"design that is used in the larger FR Series valves to provide smooth even pressure control. | Liquids air and gases that are not corrosive to bronze | TecSheet FRM, FRM-C, FRM-2 | $List Prices |
| The Types K-5 and K-5C are fully automatic back pressure valw designed to dependably maintain a predetermined pressure In a vessel or system by maintaining a predetermined vahe inlet pressure and relieving into a lower pressure line. Type K valves are not emergency relief devices, but are designed for continuous pressure regulation. | Suitable for pump systems of all kinds. Applicable on water, other fluids and especially oils of all grades. Not for steam. | TecSheet K-5, K-5C | $List Prices |
| The Types K-I0 and K-15 are fully automatic piston type back pressure valves. They are designed to dependably maintain a predetermined pressure in a vessel or system by maintaining a predetermined valve inlet pressure and relieving the exces pressure into a lower pressllre line. Type K valves are not emergency relief devices, but are designed for regulating continuous pressure. | Water, other liquids and fuel oils of all grades. Not for steam. | TecSheet K-10, K-15 | $List Prices |
| The Type KP is a pilot operated back pressure valve that offers hlgh capacty and extremely accurate control. The Type KP automatically maintains the desired maximum pressure in a vessel or system by relieving pressure in excess of the valve setting into a lower pressure return llne or to atmosphere. Type KP valves are not emergency relief devices but are contlnuous operating valves for water or air systems that offer dependable protection against over pressure conditions. | Water or air | TecSheet KP | $List Prices |
