• Suggested Installation Drawing

Pipe Not Included

The Kunkle Figure 20 relief valve is an all bronze angle pattern liquid pressure relief valve with a pressure tight cap. The cap is removed to expose a drive screw and lock nut which is used to adjust the valve to the desired pressure setting. 

(The Kunkle Figure 20 is neither UL Listed or FM approved and it is recommended that a Cla-Val 55L-60 be used for fire pump applications.)

3/4" MNPT x 3/4" FNPT

Typical installation would be for use in conjunction with a turbine style jockey pump or where the jockey pump is capable of generating pressures which exceed the working pressure of the fire protection equipment or system. 

This valve is recommended only for use as a jockey pump relief valve, not a fire pump casing relief valve.

3/4" brass check valve with 3 /32" orifice is specifically designed for use in the pressure sensing line for fire pump systems. The ¾" swing check with a 3 /32" orifice will provide adequate pressure drop in the sensing line without allowing unnecessary pump starts due to major pressure fluctuations that may be indicated in the larger diameter pipe sizes.

Brass Unions with Orifice are specifically designed for use in the pressure sensing line for fire pump systems. The unions are fitted with 3 /32” orifice which will provide adequate pressure drop into the sensing line without allowing unnecessary pump starts due to major pressure fluctuations that may be indicated in the larger diameter line. The union is only allowed to be used where the water is clear and will not allow sediment to block the hole. Check with pump manufacturer for proper use. 

Installation 

Install in the pressure sensing line according to the fire pump manufacturers recommendations using appropriate tools and sealants. Make sure excess thread sealants are not introduced inside the union during assembly. Excess sealants will clog the orifice preventing proper sensing line function.
