Figure 2
The ATT inserts are for use with four different valve housings, either:
B 1/2(15), 3/4(20), 1(25)B 1(25), 1-1/4(32)C 1/2(15), 3/4(20),1(25), 1 1/4(32) D 1(25), 1-1/4(32),1-1/2(40)
Install the selected valve housing as called for in the design drawings. Although the performance of the valve is not affected either way, industry standards call for pressure interdependent control valves (PIC Valves) to be installed on the downstream side of the terminal unit. Especially for the C and D bodies with their isolation ball valve, it is recommended to ensure the isolation valve is downstream of the PIC valve.
Note - valve selections should not be larger than pipe size.
INSTALL THE VALVE HOUSING WITH THE FLOW DIRECTIONAL ARROW POINTING IN THE CORRECT DIRECTION.
For all threaded connections please clear threads on both valve and piping of debris. Sealant such as pipe dope or teflon tape is recommended.
WHEN USING HEMP AS PIPE SEALANT, ENSURE NO STRANDS ARE LEFT IN THE VALVE OR PIPING.
The B valve body is similarly available with female-by-female threaded connections, i.e. figure 1.
ATT valves ship standard with plugs already assembled. They can be ordered with Pressure Temperature ports assembled at the factory as well, just use the Connection/Port codes that end in “P” for pressure/ temperature plugs.
The C and D valves are available with double union end connections, i.e. figure 2.
Two types of end connections are available for use with the union nut:
Threaded (male or female):The thread standard is NPT or BSP ISO 228 which is a straight metric thread (compatible with BS- 2779), depending on the end connections ordered. The threads on both the connection and piping should be cleaned carefully. As these models are union end connected, the union nuts and the end connections should be removed for installation.
O-rings are supplied with the valve body and used to seal the connections. It is recommended to grease the o-rings with silicone grease before installation.
IMPORTANT: Never use mineral oil or petrol based grease or oil on the o-rings. Please make sure the o-rings are in place in the o-ring grooves in the inlet and outlet of the valve body when installing the housing and REMEMBER TO TIGHTEN THE UNION NUTS TO ENSURE SEALING.
Soldered End (sweat):REMOVE THE END CONNECTIONS FROM THE HOUSING BEFORE SOLDERING. THIS ENSURES THAT THE O-RINGS AND INTERNAL PARTS ARE NOT DAMAGED BY HEAT.
Inserting the insert:ATT valves ship standard with your specified insert included. Inserts can be replaced keeping the valve in-line. Prior to installing the insert (supplied from factory in setting 5.0 due to calibration), the system should be properly flushed. A blank valve cover is available to be installed during flushing. It is recommended that the o-rings located around the ATT insert and at the headnut are lubricated with silicone grease, before the insert is installed into the valve body. IMPORTANT: Never use mineral oil or petrol based grease or oil on the o-rings.
The desired flow rate is chosen by adjusting the flow control insert (turned from setting 1.0 and up), with a special adjustment key, i.e. figure 3 (page 2). The key is used to adjust the scale on the top of the insert; the large white are numbered 1 through 5 and the red are numbered 1 through 9.
The insert can be installed in the valve body either before or after setting the required flow rate. Once the correct flow rate has been selected and the insert is fitted in the valve body, then the actuator is applied.
Please see specific installation instruction for selected actuator.
General.It is recommended flushing the system before installing the insert in the valve body. Suitable flushing caps are available. Water must always be suitable treated, clean and free of debris. It is recommended that a strainer be installed prior to the valve body to prevent damage or blockage due to debris. Ensure that the valve is not in the fully closed position when filling the system with water.
Warranty obligation.Failure to abide by all recommendations as per this installation and operation instruction will void warranty.
The actuator type Bray FN.0.2 is anelectrical modulating actuator supplied with a valve adaptor for easy installation.
Fitting andorientation of the actuator.Separate valve adaptor from actuator (figure 2) by pressing the green release button and turning the top part of the actuator 30° counter clockwise. Then remove the top part of the actuator from the valve adaptor.
Rotate the black knob on the valve adaptor counter clockwise (figure 3) so that the valve adaptor stem and the green indicators are in top position. Mount the valve adaptor on the insert (which must already be installed inthe valve body) and finger tighten the connec-tion union. Do not use additional tools.Never install the valve adaptor in closed position as this may damage the insert.
The piping network can now be tested if necessary by manually adjusting the valve adaptor knob.
WARNING: Do not force the knob in either direction and never adjust the black knob on the valve adaptor with a higher torque than 1 Nm.
Then place the actuator on the valve adap-tor and turn clockwise 30°, until a “click” is heard.Please do not mount the actuator more than 90° from vertical (figure 4).
