Grooved swing check is the preferred backflow prevention at fire pump discharge, sprinkler riser base and standpipe inlet. Silent check (spring-assisted wafer) eliminates water hammer in long horizontal sprinkler mains and fire pump discharge piping.<\/p>\n<h2 class=\"wp-block-heading\">UNIVAL UVSC-G product range for Toronto projects<\/h2>\n<p>UVSC-G310 is the grooved swing check with ductile iron body (ASTM A536), EPDM-encapsulated bronze disc and 300 psi rating. UVSC-W310 is the silent (spring-assisted wafer) check in matching sizes for water hammer-prone installations. UVSC-F310 is the flanged swing check (not grooved) for legacy flanged riser retrofit.
