Regulators

HD/HSP Series: Primary choice for pressure reduction or temperature control in steam application. Various pilots available for reducing pressure, controlling temperature, and other applications.
O-Series: General Purpose regulator for pressure reducing applications. Primarily used for Steam, Water, Air, and other liquids and gases. Cast Iron and Stainless Steel version available.
403 Series: The 403 Series are pilot-operated, piston-actuated, pressure regulators primarily used for reducing pressure in STEAM systems. Available with an optional internal sensing line which simplifies installation. Piston Operated regulators are more compact in size when compared to typical diaphragm actuated regulators.
455 Series: The 455 Series is an alternative to the HD Pilot Operated type regulator. These Direct Operated Regulators are less susceptible to fouling from dirt and scale. Primarily used for Steam pressure reducing applications.
B-Series: Primary regulator choice for pressure reducing applications, Water, Air, and other liquids and gases. Soft-seating provides tight shut-off, while the balanced plug and disc design allows for wider range of pressures and flows.
W91/94 Self-Op Temperature: They are recommended for controlling temperature on relatively stable systems, where small valve stroke modulations will correct temperature drift. Where sudden or large load changes, or rapid temperature changes occur, a pneumatically-actuated Control Valve should be considered.
Relief & Back Pressure Valves: Relief & Back Pressure Regulators prevent over-pressurization by relieving upstream pressure to a lower pressure region. They are designed to open and allow liquid to flow when a specific set pressure is reached. NOT FOR SAFETY RELIEF OR STEAM USE. Commonly used in pump bypass.
Ambient Regulator: The Ambi-Regulator is similar to the W91/94 Series, except the bulb and capillary are removed. This allows the thermal assembly to sense the surrounding conditions which opens and closes the valve based on ambient temperatures. Primarily used on steam tracing lines and can also be used as a freeze protection device on water lines.

control Valves

2-Way Control Valves: 2-Way valves are the most common type of control valves. These devices are capable of modulating flow at varying degrees between minimal flow and full capacity in response to a signal from external control device. Available with Pneumatic or Electrical Actuators.
Control Loop Accessories: Controllers and sensors devices to help control valve function properly and more efficiently.

Liquid Drainers

Float Type Liquid Drainers: Float Type Liquid Drainer traps use a float connected by a linkage to the valve plug to discharge condensate from the system.
Guided Float Liquid Drainers: The WLD1800/WLD1800R liquid drainers are all stainless steel and are piped vertically.
Other Drainer Types: Invert Bucket Drainers are used for the removal of water and oil from compressed air systems. Disc Type Drainers can be used for outdoor application subject to freezing.

Instantaneous Hot Water Heaters

Heat Miser: The Heat Miser is an Instantaneous Steam to Water Heater which produces hot water from steam. Our Heat miser eliminates the need for large hot water storage tanks and saves significant energy which is required for large standing tanks of hot water.
