Valves

Barber Pigging Valve is an established, reliable, and effective way of sending and receiving pipeline pigs. For decades this valve has proven its reliability in the oil & gas industry and continues to be the most cost effective environmental friendly solution to any pigging requirement. The valve sizes range from 2″ through 8″.

Figure 13 Barber Pigging Valve

The Barber pigging valve design is a simple, safe and convenient way to insert and remove flow line pigs. It eliminates excessive equipment and reduces the number of operations, thus limiting expenses and loss of product.

Construction

Materials meet API specification 6-A & 6-D, for low temperature -46C (-50F)
A.C.E standard MR-01-75 for sour service
The Valve Ball is type 300 stainless steel, surface hardened by Nitrating to resist scratching & corrosion.
Various valve coatings or material options available for customer specifications
Seat carriers are type 300 stainless steel with seat inserts of various materials to meet specified applications.
The 2″ & 3″ Barber Pigging Valves have a seat supported ball.
The 4″ through 8″ Barber Pigging Valves have a trunnion-mounted ball to reduce low turning torque.
On flow line applications that transition from 2″ to 3″ or from 3″ to 4″ the larger valve can be installed to receive and send both sizes of pigs thus simplifying applications and reducing costly expenses.

Features

Over-sized entry bore to accept swollen pigs
Entry cap vent holes to provide positive release of trapped pressure before removal.
Bleed valve connections (1/2″ NPT) to facilitate a choice between venting and draining
Integral Flanges
Easy shop/field maintenance.
Replacement parts and seal kits are readily available
Positive stop plate is easily repositioned 90 degrees on the operating stem to accommodate flow direction.
Operating stem is easily marked to verify the position of the ball
Cap lugs ensure that pigs are fully inserted into the ball cavity eliminating binding when rotating the valve

Enhanced Design Features

New seat pocket & seat design features to incorporate sealant fittings allow for on-site servicing

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.
