Description N/A Traditional bottom blowdown service requires a tandem valve. Unlike older massive designs with limited serviceability, the Clampseal® unit tandem valve offers compactness, lighter weight and easy maintainability as well as longevity of service. N/A High pressure cryogenic service demands special attention to design and quality of material and fabrication. The Clampseal® delivers tight shutoff and operability through a wide temperature range and meets ANSI B 31.3 requirements. N/A Fire-safe service is ideal for refining and chemical plants where fire safety is a major concern. Clampseal® globe valves may be retrofitted with this fire-safe capability, which meets API Standard 6FA. N/A Conval has responded to the need for a high pressure, high temperature 3-way valve with easy serviceability for both seats. Excellent service history and versatility make the Clampseal® valve the choice for 3-way service. N/A The Clampseal® Naval Boiler Blowdown valve meets the requirements of MIL-V-17737 and other applicable specifications.
