SKP15…U.. Gas Valve Actuator with

Safety Shutoff Function

Only when assembled to Series VG… Gas valves

Description

SKP15… electro-hydraulic actuators are used in combination with VG… series gas

valves to provide safety shut-off control for industrial and commercial burner

applications.

The compact SKP15… actuator opens slowly and closes immediately when power is

interrupted. The modular design allows the SKP15… to be used in combination with all

VG… series gas valve

s bodies from 1/2-inch to 6 inches 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.

Features

• UL listed, FM approved, CSA certified for USA and Canada, IRI approvable, and

ISO 9001 certified. European, Australian and Japanese approved versions

available.

• Proof of Closure with Over Travel (POC) versions are available.

• Optional NEMA 4 protection.

• Visual position indication.

• "Power on" indication light

• Quick connect wiring terminals

• Optional adjustable auxiliary switch available.

• Modular design with 360

actuator rotation for easy field wiring and installation.

• Low, 13.5 VA power consumption.

Application

SKP15… series actuators are combined with 1/2-inch to 6-inch VG… series gas valve

bodies. VG… series gas valves must be ordered separately (See VG…U... Technical

Instructions, P/N 155-512P25).

SKP15…U Electro-hydraulic Actuators Technical Instructions Document Number 155-751 November 1, 2005 Operation Figure 1. SKP15… Operation. The electro-hydraulic actuator consists of a cylinder filled with oil, a piston containing an electric oscillating pump, and a relief system. When power is supplied to the actuator, the relief system closes, and the pump moves oil from the reservoir into the pressure chamber. This action causes the piston to move downward in the cylinder, opening the gas valve.
