Emergency Shut-Off Valve

1-½" 303 Threaded
(0.5- or 7- psi versions)

Technical drawings can viewed here.

  • Manual reset
  • Very high flow efficiency eliminates pressure-drop problems when sized by building stubs that are sized in accordance with UAC tables.
  • After valve has shut off, it will not re-open regardless of valve position. (Exceeds CA-DSA & ANSI standards)
  • Soft-seat construction for positive sealing -10º F to +150º F(60 P.S.I. Max. Pressure). UL listed to -40º F.
  • Tripping mechanism has non-creeping rolling latch. (Does not develop "hair-trigger" caused by accumulated non-actuation vibrations.)
  • Visual open-close indicator.
The valve shall close within five seconds when subjected to a horizontal, sinusoidal oscillation with the following characteristics:
Peak Acceleration Period
0.3 g 0.4  seconds
The valve shall not close when subjected for five seconds to each of three horizontal, sinusoidal oscillations with the following characteristics.
Peak Acceleration Period
1)     0.4 g
2)     0.2 g
3)     0.2 g

3" 315 F Flanged
(20- or 60- psi versions)

Seismic Valves  -- Prices are FOB Lancaster.  All models are listed by UL, certified by California's Division of the State Architect (CA-DSA), and approved by Los Angeles (RR 5080). California (also know as Koso) Valves have a visual "Open"/"Closed" indicator, are installed horizontally, and remain closed when tilted or bumped.  California Valves have a factory warranty of 30 years. Seismic Actuators -- Most sized and P&T ratings are available.  These hydraulic actuators can control water, liquid propane, ammonia, high-pressure natural gas, or other fluids or gases.  Most models are flanged, and use a ball or butterfly valve.  They are pressure-to-open/spring-to-close.   Seismic Actuators are rated at 150 psi or higher.  Special fittings, seals, or metals are available.
