Type SPF-SP high capacity piston-operated steam traps

Features & Benefits

• 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.
