ST-261-I Regulating Unloader w/ chemical injector 2.1 mm

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 the 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 30.0 is recommended. A smaller nozzle may be used, but the added restriction may result in ineffective suction rates or no suction at all. In addition, remember that elbow, fittings, and even hose add to the restriction within the system and may affect or eliminate the suction capabilities.
