Type C804H-32 internal valve is part of the C404-32 Series internal valve. It utilizes a new trim seal formula designed to withstand the corrosive effects associated with Y-grade natural gas liquid (NGL) service in transport truck and large storage tank applications. This will help operators reduce premature trim replacement and process interruption, as well as lower maintenance costs. A trim conversion kit is also available for Fisher Type C404-32 4-inch internal valves.
