The ASCO Series 220 steam and hot water valves provides up to 60% more flow than competitive offerings. That means a 3/4-inch valve flow from ASCO equals the competitors 1-inch flow. The Series 220 floating PTFE diaphragm provides positive sealing and improved durability - up to four times longer than other valves. Its threaded bonnet is easy to remove for quick inspection and serviceability reducing downtime and maintenance costs. Configured with a 110 VAC voltage.

FAQS
- Hot water and steam valves are valves specifically designed and rated to handle the elevated temperatures and pressures associated with hot water systems (typically 180°F to 250°F) and steam systems (ranging from low-pressure steam at 15 PSI to high-pressure steam at several hundred PSI and temperatures exceeding 400°F). What makes them different from standard valves is the material selection — body materials must maintain strength and resist corrosion at elevated temperatures (bronze, carbon steel, stainless steel, and cast iron are common), and seal and packing materials must withstand continuous high-temperature exposure without degradation, hardening, or loss of sealing. Standard elastomeric seals (EPDM, Buna-N) used in ambient-temperature valves may soften, deform, or chemically degrade in sustained high-temperature service. Steam service valves must also handle the phase transition between steam and condensate, thermal cycling, and water hammer that can occur in steam systems. Proper valve selection for hot water and steam is critical for safety, efficiency, and long service life.
- Several valve types are commonly used in steam systems depending on whether the application requires isolation, control, safety, or condensate management. Globe valves are the traditional choice for throttling and flow control in steam systems because their design provides precise regulation and good shutoff, and they handle the high temperatures and pressures of steam service well. Gate valves are used for full on/off isolation where the valve is either fully open or fully closed — they provide full-bore, low-restriction flow when open. Ball valves (in appropriate high-temperature materials) are increasingly used for steam isolation due to their quarter-turn operation and tight shutoff. Check valves (swing and piston types) prevent reverse flow of condensate and steam, protecting equipment like boilers and pumps. Pressure relief and safety valves protect steam boilers and pressure vessels from overpressure. Solenoid valves (like the ASCO models available through Centro) provide electrically actuated on/off control for steam supply lines to heat exchangers, sterilizers, and other process equipment. Angle seat valves are excellent for steam service due to their robust pneumatic actuation and high-temperature capability.
- Water hammer (also called steam hammer) in steam systems is a dangerous pressure surge caused by the sudden deceleration or redirection of a slug of condensate (liquid water) that has collected in steam piping. When steam condenses in a pipeline, the liquid condensate can pool in low spots, and high-velocity steam flowing through the pipe can push this condensate at high speed until it hits a valve, fitting, elbow, or closed end — the sudden stopping of the heavy liquid slug creates an intense pressure shock wave that can rupture pipes, blow out flanges, damage valves, and cause serious injury to personnel. Proper valve selection helps prevent water hammer in several ways. Check valves installed in appropriate locations prevent backflow of condensate that can create water slugs. Steam traps properly sized and located drain condensate from the system before it can accumulate and travel as a slug. Slow-closing valves (globe valves with handwheels rather than quarter-turn valves) reduce the risk of suddenly blocking steam flow and trapping condensate. Properly designed warm-up procedures that gradually open main steam isolation valves allow condensate to drain before full steam flow is established.
- Hot water and steam valves require seal and packing materials that maintain their sealing properties, mechanical integrity, and chemical resistance at sustained high temperatures. PTFE (polytetrafluoroethylene) is one of the most common seat and seal materials for steam service — it handles continuous temperatures up to approximately 500°F, is chemically inert, and provides low-friction, reliable sealing. Reinforced PTFE (PTFE filled with glass, carbon, or other materials) improves the mechanical strength and reduces cold-flow (deformation under load) that plain PTFE can experience at high temperatures. Metal-to-metal seating (hardened stainless steel, Stellite, or other hard alloys) is used in the most demanding steam applications where temperatures exceed the range of polymeric seals or where fire-safe performance is required. Graphite packing is the standard stem seal material for high-temperature steam valves — it withstands temperatures exceeding 1000°F, conforms to the stem and packing box surfaces, and provides reliable sealing with low friction. For solenoid valves in steam service, special high-temperature seal materials rated for steam duty are specified, as standard elastomeric seals would rapidly fail.
- Selecting a valve for hot water or steam service requires confirming several key parameters. First, verify the operating temperature and pressure — steam systems range from low-pressure (15 PSI, approximately 250°F) to high-pressure (several hundred PSI, temperatures above 400°F), and the valve's pressure-temperature rating must cover the maximum operating conditions with an appropriate safety margin. Second, choose the right valve type for the function: globe valves for throttling and precise control, gate or ball valves for on/off isolation, check valves for backflow prevention, pressure relief valves for overpressure protection, and solenoid or angle-seat valves for automated shutoff. Third, select appropriate materials — bronze is common for low-pressure steam and hot water, carbon steel for higher pressures and temperatures, and stainless steel where corrosion resistance is needed. Fourth, confirm that the seat, seal, and packing materials are rated for the specific temperature — PTFE seats, graphite packing, and metal-to-metal sealing for high temperatures. Fifth, size the valve for the required flow rate and allowable pressure drop. Finally, verify compliance with applicable codes and standards for the specific application (boiler codes, building codes, insurance requirements).
