and maintaining your control valve. DANGER and

WARNING hazards are related to personal injury.

CAUTION

hazards

involve equipment or property

damage.

Operation of damaged equipment can,

under certain operational conditions, result in

degraded process system performance that can

lead to injury or death. Total compliance with all

DANGER, WARNING, and CAUTION notices is

required for safe operation.

This is the safety alert symbol. It alerts you to potential

personal injury hazards. Obey all safety messages

that follow this symbol to avoid possible injury or

death.

Indicates a potentially hazardous situation which, if not

avoided, could result in death or serious injury.

Indicates a potentially hazardous situation which, if not

avoided, could result in serious injury.

Indicates a potentially hazardous situation which, if not

avoided, could result in minor or moderate injury.

When used without the safety alert symbol, indicates

a potentially hazardous situation which, if not avoided,

could result in property damage.

Masoneilan 78-80S & 08-80S Transfer Valves Instruction Manual | 5

1. Overview

The Model 78-80S is a transfer valve combining a pilot valve of the oating ball type and three-port

valve into one unit and is a standard-capacity three-way transfer valve of a set pressure regulating type.

The other model 08-80S, is the same as the 78-80S except that a pilot valve is not combined and is

the so-called three-way transfer valve. If several 78-80S are needed, one 78-80S can be installed,

connecting 08-80Ss to it by mating the pilot outlet pressure (“SIG.OUT”) on the 78-80S to “SIG” on the

08-80S to simplify piping and achieve transfer.

The structures of these models are shown on pages 8 and 9.

2. Specications

• Maximum operating pressure

Body 1.72 Mpa

Signal part 1.03 Mpa

• Set pressure range: 100kPa to 700kPa

• Hysteresis: 34kPa or less

• CV value

IN→ OUT 0.8

OUT→EXH 1.3

• Connection

IN, OUT, EXH and SIGNAL connection ports: Rc 1/4 (Option NPT 1/4)

• Operating temperature range: -30°C to +83°C (option: 0°C to +100°C)

3. Certications

This instrument is certied in:

• Azerbaijan (AzSERTCENTER) • Russian Federation (CU-TR Ex)

• Armenia • Uzbekistan (UZSTANDART)

• Belarus • China (China Ex)

• Kazakhstan • and is also ATEX compliant.

4. Mounting

Clean all the pipes before mounting the valve and completely remove dust, scale and other foreign

matter. Mount the transfer valve as close to the actuator as possible and let air ow toward the IN and

OUT marks located on the lower side of the body. When using the valve as a lock-up valve, put a blind

plug in the EXH port.

Two air connection ports to the pilot part are provided on the 78-80S, one being marked SIG and the other,

SIG OUT. Connect the signal pressure to the port marked SIG. Use SIG.OUT for sending signal to the 08-

80S when it is also mounted.

The transfer valve functions to cut o󰀨 IN and to connect OUT to EXH when the signal pressure lowers

below the set pressure or is reduced to zero.

Do not use signal pressure at air pressure exceeding 1.03Mpa (10.5kgf/cm2).

Feeding signal pressure from near the IN side of the body will cause uctuations in signal and air

pressures. This may cause hunting.

5. Adjustment

The necessary settings of the transfer valve are generally performed at the factory and adjustment of

it is not required. If, however, the setting pressure needs to be adjusted, make adjustment as follows:

a) Loosen the lock screw (23) and turn the adjust knob (14) counterclockwise to release the

compression of the spring (22).

b) Turn the adjust knob (14) one or two turns clockwise to tighten it and to slightly compress the

spring (22).

c) Connect air pressure to “IN” marked on the body to check whether the body is open or closed.

Then connect the pressure gauge and pressure reducing valve to the signal pressure connection

port SIG.

d) Apply supply air pressure and set the air pressure to SIG at specied pressure by operating the

pressure reducing valve while watching air pressure to SIG on the pressure gauge.

e) Turn the adjust knob (14) clockwise until air pressure no longer leaks through “OUT” marked on

the body.

f) This will cut o󰀨 IN, and OUT and EXH will open in the transfer valve.

g) Lastly, fasten the lock screw (23) and x it.

The ball (18) temporarily oats to transfer the pilot part and the valve emits a light beat tone

when the set and signal pressures become the same. This is not an anomaly. The beating

sound will stop when the transfer ends.

6. Maintenance

Rubber is used in various parts of the transfer valve. Periodical exchange of this rubber every ve

years is recommended. Your valve will be checked and repaired at our factory if a check or a repair

becomes necessary. Contact our agent or sales o󰀩ce for a check or a repair.
