Piston cage unit: The advanced piston cage unit design combines a liner, piston, main seat and main valve into one factory-tested assembly to ensure precise alignment and simple maintenance. In the SPF Type there is also a bimetallic cage unit.
Valve seats CoCr alloy hardfaced: The main and pilot valve seats are CoCr alloy hardfaced to increase their resistance to the high degree of wear through velocity of flow, dirt and scale.
Small and lightweight design for piping convenience, no mounting brackets required.
All in one construction unit: Air vent, main valve, check valve, strainer and temperature controller are a single unit, ensuring perfect alignment and ease of maintenance.
Positive closing: As steam contacts the bimetal element, the pull closes the pilot valve, reducing the pressure on the piston. Line pressure below the main valve closes the valve tightly on the seat.
Positive condensate drainage for process work.
Check valve operation: The main valve acts as a check valve preventing back flow.
Temperature controller controls and adjusts the discharge temperature of condensate which can be calibrated using a special thermometer.
Other options include: Piping King units; thermometer; strainer blowdown valve (SP only). SPF 0-7 (only) can include a “Y” Type strainer in line to protect trap.
