1" Brass Press Ball Valve (994)

The 1" Lead Free Brass Press Ball Valve (994) brings the speed and safety of press-fit installation technology to one of the most common isolation valve sizes in commercial plumbing and mechanical systems. At the 1" size, press ball valves are most frequently found in commercial buildings, multifamily housing, institutional facilities, and mechanical rooms where 1" copper is the standard branch and distribution line size — and where the no-flame, no-solder installation method delivers its greatest advantages in occupied spaces, high-productivity project environments, and anywhere open flame is restricted or prohibited.

Press-fit connections on both ends are compatible with standard press-fit tooling and engage directly with 1" copper tubing. A single press creates a permanent, leak-free joint through the EPDM O-ring seated in each press end — no flux, no solder, no torch, no waiting for joints to cool before pressurizing the system. On a 1" line, this means a full valve installation is complete in under a minute per connection, with no fire watch required and no heat damage risk to adjacent finishes, insulation, or structural members. For contractors working in hospitals, schools, occupied office buildings, or any sensitive environment where open flame work triggers additional permitting, hot work procedures, or safety concerns, the 994 eliminates those barriers entirely.

The lead-free brass body meets NSF 372 and Safe Drinking Water Act compliance requirements — fully approved for potable water service and code-legal in all jurisdictions that mandate lead-free components on drinking water systems. NSF 61 certification covers direct contact with drinking water, satisfying the listed-material requirements of engineers, inspectors, and building owners on potable water projects of any scale.

The full port ball design maintains an unobstructed flow path equal to the pipe's interior bore when open — no restriction, no turbulence, and no meaningful pressure drop. At the 1" size on commercial distribution lines and equipment supply connections, this full port performance preserves flow capacity to downstream fixtures and equipment without the backpressure that partial-port valves introduce. The chrome-plated brass ball rotates against PTFE seats for a smooth, bubble-tight shut-off with low operating torque, and the lever handle provides fast, positive quarter-turn actuation with a clear visual indication of valve position at all times.

Rated at 200 PSI for water service, the 994 handles standard commercial and residential system pressures comfortably, and the blowout-proof stem provides an additional layer of safety in sustained pressurized service.

Industries & Applications:

• Commercial & Institutional Plumbing — At the 1" size, press ball valves are a natural fit for distribution branch isolation, riser tap connections, and equipment supply lines in office buildings, hotels, schools, and healthcare facilities where 1" copper is the standard distribution size and flameless installation is operationally preferred or code-required
• Multifamily Residential Construction — Used on 1" main branch connections, water heater supplies, and unit isolation points in apartment and condominium construction where high installation productivity and no-flame safety make press fitting the dominant installation method
• Potable Water Systems — NSF 61 & 372 certified for drinking water contact; appropriate for water distribution in any commercial or institutional building where listed lead-free components are required at every isolation and service point
• HVAC & Mechanical Rooms — The 1" size is heavily used on chilled water branch connections, hot water heating supply and return taps, fan coil unit isolation, and boiler system branch connections in commercial mechanical rooms where press-fit copper is the system standard; press installation dramatically reduces labor time versus sweat connections in densely piped mechanical spaces
• Renovation & Retrofit Projects — Press technology shines in occupied building retrofit work where existing 1" copper runs are being tapped or extended; no torch, no heat damage risk, and no disruption to adjacent finishes or occupied spaces makes the 994 the preferred valve for retrofit isolation on live systems
• Healthcare & Laboratory Facilities — Flameless installation is frequently required or strongly preferred in hospitals, research labs, and sensitive institutional environments; press ball valves are increasingly specified as the standard isolation valve in these settings at the 1" size where branch distribution is most common
• Fire Suppression Support Systems — Used on auxiliary water supply connections, test and drain lines, and branch isolation points adjacent to wet sprinkler systems where corrosion-resistant, flameless installation is required on support piping
• Light Industrial Utilities — Suitable for process water, cooling water, and compressed air applications on 1" copper systems within the rated pressure and temperature envelope where press installation speed reduces maintenance downtime
