Swagelok® Relief Valves
Swagelok® proportional relief valves provide overpressure protection in general industrial applications with a variety of set pressures available. Bleed and purge valves provide effective bleeding, venting, or draining of signal line pressure to atmosphere.
View Relief ValvesSwagelok® R series proportional relief valves open gradually as pressure increases, providing simple, reliable overpressure protection, protecting workers, and helping to maintain proper process conditions. Set pressures can be configured at the factory or easily adjusted in the field to suit changing operating conditions. Swagelok® RV series medium-pressure relief valves can be used in applications with operating pressures up to 20 000 psig (1378 bar).
Swagelok® PRV series proportional safety relief valves are certified to PED 2014/68/EU Category IV and CE-marked in accordance with the Pressure Equipment Directive as a safety valve according to ISO-4126-1. They are factory-set, tested, locked, and tagged with the set pressure.
Swagelok® BV series bleed valves can be used on instrumentation devices such as multivalve manifolds or gauge valves to allow safe removal of instruments and to assist in the calibration of control devices. They are available with low emission (Low-E) certification according to API 624 to combat fugitive emissions.
Swagelok® P series purge valves are manual bleed, vent, or drain valves. Knurled caps are permanently assembled to valve bodies for safety, and both bleed and purge valves are compact for convenient installation.

하나의 새로운 밸브, 반도체 제조 기술을 바꿀 수 있는 세 가지 이유
혁신적인 최신 원자층 증착(ALD, Atomic Layer Deposition) 밸브 기술이 어떻게 첨단 기술 반도체 제조 시장을 변화시킬 수 있는지 소개합니다.
비례식 릴리프 밸브
R 시리즈 비례식 릴리프 밸브는 다양한 액체 및 기체 일반 산업용 애플리케이션에서 간단하고 신뢰성 높은 과압 방지 기능을 제공하며, 10~6000 psig(0.7~413 bar)의 설정 압력을 지원합니다. 이 제품은 압력이 증가하면 점진적으로 열리며, 시스템 압력이 설정 압력 아래로 떨어지면 닫힙니다. PRV 시리즈 비례식 안전 릴리프 밸브는 다섯 가지 설정 스프링 압력 범위를 선택할 수 있는 인증된 안전 밸브이며, 원하는 설정을 보장할 수 있도록 선택한 설정 압력이 출고 시 설정 및 테스트되고, 잠금과 태그가 적용됩니다.
블리드 및 퍼지 밸브
Swagelok 블리드 밸브는 계장 제거 전 또는 제어 장치의 캘리브레이션을 진행할 수 있도록 신호 라인 압력을 대기로 벤트하는 데 사용할 수 있습니다. 수나사 NPT 및 SAE 연결구로 공급 가능합니다. 퍼지 밸브는 NPT, SAE, Swagelok® 튜브 피팅 또는 튜브 어댑터 연결구가 포함된 수동 블리드, 벤트 또는 드레인 밸브입니다.
