Safeguard complex systems' sensitive equipment by controlling varying inlet and upstream pressures despite varying flow demands.

Ensure safe and efficient gas supply with our high-quality gas cylinder regulators and changeover regulators. Trust us for reliable gas control solutions!

Achieve precise and consistent control over pressure fluctuations, irrespective of variations in flow rate or inlet pressure.

Swagelok pressure regulators are designed, manufactured, assembled, and tested according to rigorous standards to ensure the quality and reliability you demand from our products.

Swagelok RHPS series deliver precise pressure control in process fluid systems up to 4 in. (101 mm) in a variety of spring-, dome-, and air-loaded pressure regulators.

Precisely control inlet pressure, ensuring consistent process output and performance across various industrial applications.

Time delay is often underestimated or misunderstood in analytical systems. One way to mitigate this delay is with a pressure-controlled regulator. Learn how to manage your analytical system’s time delay with these tips.

Reliable pressure control is essential to the safe operation of your fluid systems. At Swagelok, we have the right combination of high-purity and industrial pressure regulators to fit practically any situation. Pressure control advisors located around the world can help you find a configuration that will maintain pressure and minimize droop over a wide range of pressures and flows.

Maintain process outputs within chemical distribution, DI water, and chemical delivery systems with the right pressure-reducing, spring-loaded regulator.

Swagelok’s single- and two-stage spring-loaded and instrumentation regulators (K series) and process pressure regulators (RHPS series) deliver consistent pressure control to maintain predictable process outputs in a variety of industrial applications. High-purity, high-flow regulators (HF series) provide reliable pressure control in applications that require uncompromising process cleanliness.

From laboratory benches to busy manufacturing facilities and commercial fueling stations, industrial pressure regulators play a crucial role in ensuring fluids are contained and transferred under optimal pressures. If pressure cannot be properly controlled in these applications, test results may be invalidated, processes may be disrupted, equipment may be damaged, and personnel may be put at risk. You need to know the regulators in your system will consistently and accurately maintain pressure levels over extended operating lifespans—all without requiring frequent maintenance, repair, or replacement.

Refunds We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method. Please remember it can take some time for your bank or credit card company to process and post the refund too.

Swagelok has advisors on fluid systems located at authorized sales and service centers around the world to provide local support in choosing between a spring-loaded, a dome-loaded, or one of the many other available regulator configurations. These advisors can also help diagnose regulator problems and customize and build fluid systems that include regulators such as a gas distribution system.

Swagelok pressure regulators provide the consistent, accurate, and lasting performance needed to operate fluid systems safely, reliably, and cost-effectively.

Exchanges The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.

Swagelok® manual HF series high-purity pressure regulators are available as compact inline or modular-surface mount models with flow rates up to 200 std L/min.

Supply pressure effect, also known as dependency, is an inverse relationship between inlet and outlet pressure variables within a regulator. Learn how to manage this phenomenon in your pressure regulators with tips from Swagelok.

Design systems more efficiently with manual adjustability, high-flow capacity, and a corrosion-resistant design for dependable gas control.

Swagelok® HF series are high-flow, high-purity pressure regulators available in compact preset or dome-loaded models with flow rates up to 300 std L/min.

Droop, or the decrease in outlet pressure as downstream flow increases, can be an issue for all regulators. Watch this video to discover considerations for minimizing droop in a pressure-reducing regulator.

Enhance accuracy and stability with an electrically heated vaporizing pressure-reducing regulator, ideal for vaporizing liquid samples or preheating gas samples.

Maintain regulators and reduce downtime with OEM rebuild kits. Kits include wetted components, lubricant, and instructions.

Whether you need to maintain pressure downstream or upstream in an analytical or instrumentation setting (K series) or control pressure in a challenging industrial environment (RHPS series), a high-purity, high-flow application (HF series), or a system with storage tanks containing hazardous fluids (tank blanketing), we have a configuration to meet your needs. Find detailed product information, including materials of construction, pressure and temperature ratings, options, and accessories in the product literature provided here.

This 3/4 inch temperature and pressure relief valve is used in water heater and hot water storage tank applications to provide automatic temperature and pressure protection to hot water supply tanks and hot water heaters up to 105,000 BTU/hr. It features a brass body with NPT male inlet and NPT female outlet connections, unique thermostat with special thermo-bonded coating, and a test lever. It is ASME rated and CSA listed. The temperature relief is at 210 degrees F (99 degrees C), and the pressure relief is 100 psi (7.0 bar).

Swagelok offers pressure-reducing and vapor recovery (back-pressure) tank blanketing regulators for systems requiring an inert gas in the vapor space of a storage tank.
