世伟洛克® R 系列比例卸荷阀会随着压力的升高而逐渐开启,提供简单可靠的超压保护、保护工人安全并帮助维持适当的工艺条件。设定压力可以在出厂时进行配置,也可以在现场轻松调节,以适应不断变化的运行条件。世伟洛克® RV 系列中压卸荷阀可用于工作压力高达 20 000 psig (1378 bar) 的应用场合。
世伟洛克® PRV 系列比例安全卸荷阀已通过 PED 2014/68/EU IV 类认证,并依据 ISO-4126-1 标准作为安全阀,按照压力设备指令加贴了 CE 标志。这些阀门出厂时即已设置、测试、锁定并标记了设定压力。
世伟洛克® BV 系列排放阀可用于多阀阀组或压力表阀等仪表设备上,以便安全拆卸仪表并协助校准控制设备。这些阀门已获得符合 API 624 标准的低排放 (Low-E) 认证,以减少逸散性排放。
世伟洛克® P 系列吹扫阀是手动排放、放空或排空阀。为确保安全,滚花帽永久性地装配在阀体上,而且排放阀和吹扫阀均结构紧凑,便于安装。

How to Isolate Industrial Fluid Systems with Block Valves
The isolation of industrial fluid system lines prior to maintenance is vital to plant safety. One of the safest ways to isolate a fluid system line is to install two block valves. Learn how to design proper configurations for your system.

One New Valve. Three Reasons It Could Change Semiconductor Manufacturing
Find out how the latest innovation in atomic layer deposition (ALD) valve technology is changing the game for high-tech semiconductor manufacturers.

Proportional Relief Valves
R series proportional relief valves provide simple, reliable, overpressure protection for a variety of liquid or gas general-industry applications with set pressures from 10 to 6000 psig (0.7 to 413 bar). They open gradually as the pressure increases and will close when the system pressure falls below the set pressure. PRV series proportional safety relief valves are certified safety valves with five set spring pressure ranges are available with the selected set pressure factory-set, tested, locked, and tagged to ensure the desired setting.
Bleed and Purge Valves
Swagelok bleed valves can be used to vent signal line pressure to atmosphere before removal of an instrument or to assist in calibration of control devices. Male NPT and SAE end connections are available. Purge valves are manual bleed, vent, or drain valves with NPT, SAE, Swagelok® tube fitting, or tube adapter end connections.
