产品名称:Reserve Capacity Relief Valve (RCRV) Low Temperature Storage
简要介绍:Designed to provide overpressure protection on low pressure, low temperature storage tanks when a large volume of vapor is generated by unusual conditions. O-ring seat provides bubble-tight performance to 95% of set pressure. Full open at set pressure – no overpressure required to achieve rated capacity. Features & Benefits: Soft Seat – An O-ring seat provides bubble-tight performance to 95% of set. Tension Link – The valve is held closed by a combination of tension link and spring force, to provide positive opening at set and bubble tight shut-off at reseat. Full Open at Pop – No overpressure required for rated capacity. Maintenance – All parts requiring maintenance can be replaced with the valve installed, with the tank pressure at 50% or less of set.

产品名称:Internal Tank Valves (ITV) Liquid Storage: LNG, LPG, NH3, LOX
简要介绍:The Anderson Greenwood Internal Tank Valve is designed to satisfy all of the requirements of NFPA No. 59A for this type of installation, specifically, paragraph 6333: The design and installation of an internal valve shall be such that any failure of the penetrating nozzle resulting from external pipe strain will be beyond the shut-off seats of the internal valve itself. ”The ITV is designed for long trouble-free life. Design features are simple yet rugged to withstand the rigors of construction. No maintenance of the ITV is required after installation. When mounted on the tank bottom, this valve allows near 100% withdrawal of liquid. It does not depend upon counter-weights or actuator forces for closing. The fail-safe condition of the ITV is closed. A block valve is always to be provided in series with this valve. The downstream block valve must be closed before the ITV can be opened. This prevents the ITV from being opened on an open or ruptured downstream line. Seal ruggedness and long life are evaluated as more important factors than absolute leak tightness. The seal may be installed as a separate unit. The use of this valve increases safety, minimizes property requirements, and should lower insurance liability.
