Description

The Sutner brand ST261 unloader is a favorite for certain applications that require durability, longevity, and tamper proof pressure regulation. In the world of higher pressure is desirable sometimes these regulating unloader valve can be manually over adjusted by an uninformed operator. 

We like this Suttner  brand unloader for the rental and construction industries in particular and when maintenance cleaning crews are rotated frequently and training it’s not always ideal.

The downstream chemical soap injector is included, chemical tube and filter sold separately.

We invite you to speak with a pump specialist by calling 1-800-333-9274 during business hours.

FEATURES:
  • Regulating unloader valve
  • Tamper resistant operator adjustable valve which allows limit setting on both maximum and minimum pressure
  • Ideal for steam combination applications
  • Straight flow-through design minimizes pressure loss through valve
  • Working components constructed of high grade stainless steel, teflon, and Viton seals for maximum heat/chemical resistance
  • Internal bypass valve can be easily accessed and repaired without removing unloader from unit
  • True to Suttner design tradition, valve is cartridge type and installed in minutes
  • Pressure adjustment knob can be removed if desired

SPECIFICATIONS:

  • Downstream injection at 10:1 ratio
  • Low pressure limit setting eliminates need of additional metering devices
  • Relies on pressure loss through a restrictive orifice, which is built-in on the ST-261. Restriction AFTER the orifice must be minimized in order for injection to occur. Therefore, this system must incorporate a large orifice spray nozzle which reduces such restriction. The usage of a nozzle with a minimum orifice size of 3.0 is recommended. A smaller nozzle could be used, but the added restriction may result in ineffective suction rates or no suction at all. In addition, remember that elbows, fittings, and even hose add to the restriction within the system and may affect or eliminate the suction capabilities
