Each valve is tested using a helium mass spectrometer leak detector calibrated for a minimum sensitivity of 2x10-10 Std. Atm. cc/sec of He. Internal welds are inspected for pits, cracks, and other irregularities which may cause virtual leaks. Carriage and gate mechanism may be removed through the bonnet flange for seal replacement, cleaning or retrofitting without removing the valve body from the system. Actuators are constructed with non-rising Acme threads for smooth and quick operation. Visual open position indicators are standard on all manual valves. Products & Services
Valve repair services repair and rebuild used valves.
Non-destructive testing (NDT) equipment is used to detect, inspect, and measure flaws, bond integrity, and other material conditions without permanently altering or destroying the examined part or product.
Solenoid valves are devices that use a solenoid to control valve activation.
Vacuum valves are used when a vacuum must be maintained in a closed system.
Tempering valves and thermally actuated valves contain a thermal sensing component that opens or closes in response to temperature changes.
