Siemens Combustion SKP55.013U1 Gas Valve Actuator with Safety Shutoff 120V

Description:

Siemens SKP55.013U1 Gas Valve Actuator with Safety Shutoff 120V SKP55… pressure regulating electro-hydraulic actuators are used in combination with VG… series gas valve bodies to provide shut-off and air/gas ratio control for industrial and commercial burner applications. The SKP55… actuator controls the pressure difference across a restriction in the gas supply line as a function of the pressure difference across a restriction in the air supply duct so that the air to gas ratio remains constant irrespective of air volume changes. There is no need for an upstream constant pressure regulator when using an SKP55… actuator within the applicable pressure range of the VG… valve body. Since three functions: safety shut-off, constant pressure regulation, and air/gas ratio control can be performed by a single valve, fewer gas train components and fittings are required. This significantly reduces both the size and weight of the gas train. In addition, smaller diameter gas valves can be used. The compact SKP55… actuator opens slowly and closes immediately when power is interrupted. The modular design allows the SKP55… to be used in combination with all VG… series gas valves bodies from 1/2-inch to 6-inch in size The actuator is easily mounted on the square flange of any VG… valve with four pre-mounted screws. A visible position indicator on the front of the actuator displays the entire stroke of the valve. A light indicates when the actuator is powered. SKP55… series actuators are combined with 1/2-inch to 6-inch VG… series gas valve bodies. VG… series gas valves must be ordered separately Features: UL listed, FM approved, CSA certified for USA and Canada, IRI approvable, ISO 9001 certified; European, Australian and Japanese approved versions available. Safety shut-off function, pressure regulating function and air/gas ratio control in one compact unit. Proof of Closure with Over Travel (POC) versions are available. Optional NEMA 4 protection. Simplifies commissioning and reduces start-up time for: Recuperative burners with combustion air preheating. Burners with continuously variable air or gas nozzle openings in the burner head. Burners where either the air or gas pressure is not representative of the actual flow. Burners with negative combustion air pressure levels. Maintains air/gas ratio when the airflow is disrupted. Automatic compensation for combustion chamber back pressure fluctuations. No mechanical wear or play that causes drifting. Visual position indication. "Power on" indication light Quick connect wiring terminals Optional adjustable auxiliary switch available. Excellent tracking characteristic. Modular design with 360o actuator rotation for easy field wiring and installation. Low, 13.5 VA power consumption.
