The V4730C/V8730C/V4734C 1:1 Gas/Air Servo Regulated Gas

Valves, with the addition of the Venturi Mixing Unit (VMU) and dc

fan, are used for modulating premix appliances such as gas bur-

ners, gas boilers, rooftop units, makeup air units and process ap-

plications.

pressure within 5 seconds.

Maximum Allowable Leakage:

Outerwall: 3 cu. in./hr (50 cm3/h) at test pressure of 0.87 psi

(6 mBar) and 7.83 psi (540 mBar).

First Valve: 2.5 cu. in./hr (40 cm3/h) at test pressure of 0.87 psi

(6 mBar) and 7.83 psi (540 mBar).

Second Valve: 2.4 cu. in./hr (40 cm3/h) at test pressure of

0.87 psi (6 mBar) and 7.83 psi (540 mBar).

High Pressure Test:

In the OFF condition, the valve will withstand 21.75 psi (1.5 Bar)

inlet pressure without damage.

Accessories:

FL020008 Mesh Screen.

Flange Kits (see Table 2).

DIN43650 Connector

32006653-001 Venturi O-rings/screws.

Operational Voltage Range:

The combination gas valve will function satisfactorily between

85% and 110% of the rated voltage.

Gas Valve Connection to Venturi (Field-Assembled):

Four screws and an O-ring are used to connect the gas valve to

the venturi/manual shutoff valve.

The metal tube provided with the venturi must be connected bet-

ween the venturi and the gas valve regulator.

Fan Connection:

The venturi is connected to the fan using six bolts (wich are inclu-

ded with VMU).

Minimum Load:

The minimum load for which the system can be used is

14-17% of the reference load, which equals a minimum

pressure differential of 0.2 in. wc (50 Pa) of the 1:1

venturi/servo regulator gas control.

Approvals:

Gas Appliance Directive 90.396/EEC

ANSI: Z21.21

CSA: 6.5
