Product Description

Honeywell VQ425MA1021 COMBINATION VALVES CLASS A DN25 360MBAR Air Solenoid Valves For Gas Burner/Boiler

APPLICATION

The VQ400M Series class “A” safety combination valves are used for control and regulation of gaseous fluids in gas power burners, atmospheric gas boilers, melting furnaces, incinerators and other gas consuming appliances. The VQ400M offers flexibility to mount accessories like valve-position indicator, pressure indication switches, vent-valves or by-pass valves at several positions at the gas valve, whenever, wherever.

These combination valves are available in two body sizes:

• Small model

o VQ420

o VQ425

• Large model

o VQ440

o VQ450

All models are connected at suitable sized gas pipes by flange kits which can be ordered separately in several sizes.

FEATURES

• Class “A” safety combination valve for control of gaseous fluids in gas consuming appliances in accordance with international standards.

• Main body with two gas valves with single seat.

• Possibility of installing internal by-pass valve to achieve high-low flame control.

• Possibility of installing internal or external pilot valve.

• Possibility of installing vent
valve.

• Possibility of installing flanged minimum and maximum pressure switches.

• Possibility of installing valve Proving System (VPS).

• Possibility of mounting Closed Position Indication switch (CPI) at bottom of safety valve V1 and / or valve V2.

• Closing time: < 1 second.

• Coils field replaceable.

• Coils suitable for permanent energizing.

• Fine mesh screen between inlet flange and main body (optional).

• Various pressure tap points at main body available

• Second main valve, either with adjustable flow regulator (fast), or characterized opening mechanism (slow) with adjustable maximum flow rate and step pressure.

• Rectifier boards field replaceable.

• PG11 cable strain relief standard at VQ400M.

• Plug connector according to ISO 4400 / DIN EN 175301-803 optional for VQ400M.

DESCRIPTION

The VQ400M Series combination valves are suitable for the control of gaseous fluids in gas consuming appliances according to international standards.

The VQ400M Series combination valves meet the class “A specification according EN161. The VQ400M Series combination valves can be ordered with straight flanged pipe connection from 1/2 " up to 2". The VQ400M Series combination valves are standard equipped with two safety valves V1 and V2. The first valve (V1) is always fast opening. The second valve (V2) can be either fast or slow opening.

• Standard the second valve (V2) is supplied with throttle screw (fast opening with flow regulation).

• Optionally the second valve (V2) can be ordered with slow opening device (with flow regulation and adjustable opening).

• Optionally the second valve (V2) can be ordered fast open, without any regulation device.

Opening time

The first valve (V1) opens in less than 1 second. The second valve (V2) can be either a fast opening valve which opens in less than 1 second or a characterized opening valve which is adjustable from 1 up to 30 seconds, at rated capacity.

The opening characteristic is factory set at approximately 6 seconds at the following conditions:

• measured at 80 % of rated capacity
• 30 mbar supply pressure

• nominal voltage

• 20 °C

• 2,5 mbar pressure drop

• no step pressure

Due to the influence of ambient temperature (-15 ... 60 °C) the adjusted opening time of 6 seconds measured at 80% of adjusted flow rate can vary +/- 4 seconds.
