FEATURES

RV284B

High flow capacity, low pressure loss.

BSP or compression connections.

Test point to check for correct operation.

WRc Approved.

RV284A

DZR brass body.

Conforms to BS6282 Part 1.

APPLICATION

The RV284A and RV284B check valves conform to BS6282 Part

1 and are WRc Approved for use in potable water. These valves

can be used on either cold or hot water up to 90˚C and meet the

SINGLE CHECK VALVES

RV284A/B

Installation

The RV284A and RV284B check

valves should be installed with the

flow in the direction of the arrow on the

body. Care should be taken when using

jointing compounds not to allow excess

material to enter the valves as this

could prevent tight shut-off in reverse

flow conditions. The valves will operate

in any orientation and are silent in

operation. All RV284 single check

valves are provided with a 1 ⁄ 4 ” test point

to ensure correct functioning.
