Siemens skp 25.003 e2 user manual. Actuators for gas valves Siemens SKP25. General information about actuators
Electrohydraulic actuators Siemens SKP25.003E2 together with valves (VGG..., VGH..., VGF..., VGD2..., VGD4..., VRF..., VRH..., VLF...) designed for use with petroleum gases I-III and air. As a rule, they are used on gas-fired heat generators. The Siemens SKP25.003E2 gas valve actuator operates as a constant pressure regulator with a setpoint spring. Together with the valve provides the shut-off function safety valve with gas pressure regulator / controller. This drive is mainly used with gas burners with forced pressurization (with mechanical or electronic control of the mixture of fuel and air). Siemens SKP25.003E2 servomotors open slowly and close quickly. They have low power consumption. Detachable connection, travel indication and electrical operation indication are provided. Actuators SKP25.003E2 are supplied without a limit switch.

Gas valve actuator SKP25.003E2
The SKP 25.003 E2 actuator for Siemens gas valves is an actuator, or as it is also called, the SKP-25.003E2 actuator for Siemens valve are equipped with a pneumatic bypass controller that provides one-stage opening or closing of the valve. The pumping pump is located inside the oil chamber. The gas valve actuator spring is replaceable and can be matched to different operating pressures. Plug connections, connecting cable, stilling throttle, springs and additional seals can be purchased separately with the valve (option) or separately. The SKP 25.003E2 actuator provides fast closing and slow opening of the Siemens gas valve. The SKP25 actuator works as a pressure regulator in various ranges (pressure range depends on the type of setpoint spring used. The SKP25... actuator controls the bypass valve via the pneumatic controller, opening the gas valve. Used on gas valves (mounted) on fan-type forced draft burners with mechanical or electronic fuel/air ratio control.
