Redefining Efficiency and Safety: Assured Automation Introduces New Thermal Shutoff Valves With the TSV Series

ROSELLE, N.J., Aug. 15, 2023 /PRNewswire/ — Assured Automation, a leading provider of automated valves and flow components, proudly announced the launch of its new product. The TSV Series integrates innovative technology and rigorous safety standards to deliver valves that are reliable, easy to maintain, and supremely functional, all while keeping safety at the forefront.

Assured Automation: TSV Series ( 

TSVs are critical components in refinery, terminal, and chemical piping systems. Thermal activated shutoffs work like fuses in the pipes that carry flammable liquids, and in the event of a fire, shuts the fuel flow down, preventing these liquids from further accessing and feeding the flames. Thermally activated shutoff valves can be used in a wide variety of applications at refineries, marine terminals, chemical plants and alcohol lines.

“Our TSV Series is a significant innovation in safety systems,” said Assured Automation. “It combines a fire-safe ball or butterfly valve with a pneumatic actuator and an FM-approved FireChek® valve, providing a comprehensive thermal shutoff solution. It’s a testament to worldclass engineering and our commitment to safety and quality.”

Key features of the TSV Series include:

1.  A fire-safe ball or butterfly valve-ball valves come with NPT, Socket Weld, or 150# or
300# ANSI Flanged connections. Butterfly valves are available with 150# or 300# ANSI
Flanged connections in lugged or wafer style. All valves are available in Carbon Steel or
Stainless Steel and are fire-safe with graphite seals. In addition, they are Fire-Safe designed to API 607-5; with bodies designed in Carbon Steel or Stainless Steel.

2.  A spring return pneumatic valve actuator. The C Series pneumatic actuators offer a simple but cost-effective solution for use on quarter turn (90 degree) ball and butterfly valves.

  • Temp Range: -4°F to +175°F
  • Supply Pressure:
  • Spring Return: 40 to 120 psi
  • Double Acting: 20 to 120 psi
  • Torque Output: up to 40,000 in-lbs. (at 80 PSI supply pressure)
  • Service Life: Up to one million cycles
  • Mounting/Shaft: ISO 5211/Female

3.  A FireChek® heat-activated pneumatic shutoff valve. FM approved FireChek® thermal
exhaust valve blocks air supply and opens actuator exhaust port, allowing valve to close
when heat is detected. The FireChek® is resettable and field testable. When the thermal shutoff senses temperatures above the shape memory alloy’s actuation level, the shape 
memory element simultaneously vents pneumatic actuator air pressure and closes
upstream supply pressure. A manual reset allows routine performance testing for safety
maintenance programs. Other specs include:

  • Actuation Temperature: 135°F, 150°F, or 165°F
  • Maximum Working Control Pressure: 125 PSIG
  • Fill and Discharge Capacity: 1 liter of air in under 1 second at 125 PSIG
  • Cv: 0.49
  • Length: 2.59″
  • Diameter: 1″
  • Weight: 0.482 lbs.
  • And more, including options like Explosion Proof Limit Switches, Wireless Alarm Systems, Trigger Temperatures, and compact rechargeable air compressors for charging.

4.  A Schrader (check) valve. The assembly is charged with air/nitrogen and is locked in position with a bubbletight Schrader valve which can be charged with a small air tank or with an optional battery pump from Assured Automation.

Assured Automation’s commitment to quality is clearly illustrated by its ISO 9001:2015 certification and ITAR compliance, meeting the strictest standards for military applications.
