Modular Gas Safety Shutoff ValvesSuited for use industrial boilers, furnaces, ovens, heating equipment, gas generators and kilns, gas safety shutoff valves have a compact double-valve footprint and high flow rates. The 8214(200) Series two-way normally closed solenoid valves can be used for fuel gases up to 5 psi. The V710(B)/AH(E) Series two-way normally closed electrohydraulic actuated valves can be used with fuel gases up to 15 psi. This series is available with fast- and slow-opening constructions. Both product families come in 0.75 to 3" pipe sizes and have aluminum body constructions with pressure taps up and downstream.

Single-Ended Recuperative Burner
Single-ended recuperative burner offers improved efficiency to help users save energy. The finned combustor provides increased heat transfer surface. The design also provides improved heat flux and temperature uniformity. According to the manufacturer, it cuts fuel costs over sealed ambient burners. Model SER v5 is intended for use in any indirect-fired application. It has been designed for use in continuous or batch-type furnaces.

Multifunction Gas Shutoff Valve Actuators Simplify Installation
All electrohydraulic actuators in the SKP Series can be used in combination with any of the company’s VG Series gas valves. The modular approach creates a matrix of valve combinations, allowing manufacturers to meet varied capacity and pressure regulation requirements with minimal inventory. The actuators fit all valve sizes from 0.5 to 6. Features include a visual stroke position indicator; optional proof-of-closure overtravel switch; and optional auxiliary position switches. Model SKP25 performs both safety shutoff and gas-pressure regulation, eliminating the need for a separately piped pressure regulator.

Gas Infrared Burner
Noted for endurance in bad environments, Model RL-130A can be positioned side by side, end to end, in a single or dual line, in a U shape or in a sawtooth pattern. Mounting on a manifold adapter with a single socket head screw eases replacement. Each unit has a 100 percent radiating face without exposed metal for maximum efficiency.

Mat for Blue-Flame Use
Metal fiber burner heads are intended for clean premix combustion. A lightweight mat made of FeCrA1M alloy fibers, G-mat is intended for blue-flame burner applications. It is designed to be added onto existing perforated sheet metal burners to reduce NOXbelow 10 ppm. The fabric mat insulates the heat and provides a hot combustion bed for the stable combustion of a full aerated fuel/air mixture. Modulation is up to 10:1 in blue flame mode.
