Positioning Pilot Valve Model #X

This multi-purpose, direct acting, 3-Way positioning pilot valve is actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The pilot directs flow and pressure between its ports: When sensed pressure is above set point, it connects port “C” to “0”. When sensed pressure is equal to set point, … Continued

Altitude Positioning Pilot Valve Model #8

This high sensitivity, direct acting, 3-Way positioning pilot is actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The pilot directs flow and pressure between its ports:  When sensed pressure is above set point, It connects port “C” to “0”  When sensed pressure is equal to set point, … Continued

Pressure Reducing Pilot Valve Model #82

This pilot integrates all principal functions of a 2-Way control circuit in a single assembly. It is a high sensitivity, direct acting pilot valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. When used in a pressure reducing circuit, the pilot modulates closed as downstream pressure rises … Continued

Pressure Sustaining Pilot Valve Model #83

This pilot integrates all principal functions of a 2-Way control circuit in a single assembly. It is a high sensitivity, direct acting pilot valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The pilot modulates open as upstream pressure rises above set point. An integral needle valve … Continued

4-Way Bi-Level Vertical Float #66

This 4-Way, adjustable, last position bi-level vertical float, is actuated by the float sliding along the rod assembly to either pull it down or float it up, switching the float pilot position. When the float is between the adjustable high and low level stoppers, the main valve remains in its last position. The float pilot … Continued

Model #2PB / FP#2PBL

  The model #2PB is a direct acting, single seated spring loaded diaphragm pressure reducing pilot valve. It is actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the pre-set and field adjustable spring force. It’s fully balanced poppet design ensures high accuracy and stability. When installed as a Pressure Reducing pilot valve on a … Continued

Model FP#2-UL

  This pilot valve integrates all the principal functions of a two-way control circuit into a single assembly. It is a direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. When used in a pressure reducing circuit, the pilot valve modulates to close as downstream pressure rises above set point. … Continued

Model FP#3UL

  This pilot valve integrates all the principal functions of a two-way control circuit into a single assembly. It is a direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. When used in a pressure relief/sustaining circuit, the pilot modulates to open as upstream pressure rises above set point. … Continued

Model PORV-0

  The PORV is a direct acting on/off valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The PORV is held closed by pneumatic or hydraulic pressure, sensed at its control chamber (under the diaphragm). It opens in response to a pressure drop of the wet/dry pilot … Continued

Model PC-3Q

This pilot valve integrates all the principal functions of a two-way control circuit in a single assembly. It is a direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The pilot opens as upstream pressure rises above the set point. An integral restriction acts as … Continued

Model PORV-A

The PORV-A is a direct acting on/off valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The PORV-A is held closed by pneumatic or hydraulic pressure, sensed at its control chamber (under the diaphragm). It opens in response to a pressure drop of the wet/dry pilot line … Continued
