Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions (IM-P045-10) supplied with the product. Installation note:
The valve should be installed in a horizontal pipeline with the direction of flow as indicated by the arrow on the valve body. BRV2SP and BRV2BP: When external pressure sensing is used, remove the blanking plug ( 16 ) and fit the 1/8 " /6 mm O/D compression fitting ( 17 supplied). The other end of the 6 mm sensing pipe should be connected into the downstream pipework at least 1 m (3.28 ft) downstream from the valve. How to order Example: 1 off Spirax Sarco DN15 BRV2S pressure reducing valve with SG iron body flanged EN 1092 PN25, stainless steel bellows and fitted with an orange spring for downstream pressure control of 3.5 to 8.6 bar g.
