Slab gate valves by Daniel Valve provide a spring-loaded seat/floating gate combination that provides low and high pressure seal; seat faces that are outside the flow stream in the fully open or closed position considerably extending seal life; two-piece stem design simplifies motor operator mounting; full thru-conduit port for passage of pigs, wipers, and scrapers; internal pressure relief to upstream side; secondary stem seal/packing injector; top entry for inline maintenance and double block and bleed. Daniel says its Valve Model M303A is an advanced fabricated body design slab gate valve manufactured and tested to API-6D.
