Saf-T-Matric ESD Valve

Saf-T-Matic ESD Valve

This is an essential component for all flow line applications. It is a highly dependable safety valve which automatically controls the shutdown of flow lines when pressures exceed, or fall below, pre-determined limits.

This Valve can be used in various applications including oil well flow lines, gas lines, hydraulic lines, or in any situation requiring high and low pressure limits.

It provides complete line protection of high pressure overloads and/or loss of fluids in the case of a line rupture. The working pressure for the Saf-T-Matic Valve ranges from 15 psi to 15,000 psi

Design Advantages

Fail-Safe

The Saf-T-Matic surface shut-down valve is held open by control pressure in the Direct Control, Remote Control or Pilot Control Head. A loss of this control pressure, or a mechanical failure within the unit, will close the valve without the assistance from another power source.

Manual Opening

Once the Saf-T-Matic closes, it must be opened manually to return it to service. This safety feature prevents accidental automatic opening before desired or required. The balanced stem of the valve allows ease of reopening against high body pressures.

Versatile

The Saf-T-Matic offers several safety system shutdown options including Direct Operated, Remote Operated, Pilot Operated and in combination with other devices and equipment as required by the customer.

Adaptable

Saf-T-Matic valves can be matched to any standard connection and may be installed on wellheads, flow lines and at many other points requiring safety shutdown systems.

Wide Operating Ranges

The Saf-T-Matic valve can operate with control pressures ranging from 15—15,000psi.

Straight-Through Flow

Bore alignment reduces flow turbulence, erosion and pressure drop. Pressure drop is taken at the outlet seat to reduce the possibility of formation of hydrates in the valve.

Non-Freezing

The Saf-T-Matic does not vent to atmosphere. This reduces or eliminates the possibility of freezing of the control head Mechanism.

Field Setting

Pressure settings of the Control Heads may be changed in the field while the valve is in service.
