Array actuators are designed to be used as safety and

control systems in drilling, wellhead, distribution and storage

applications both on and off-shore.

the sole purpose of every actuator manufactured by Array is

to control the flow of volatile, often toxic, liquids and gases and

keep them from being emitted into the atmosphere or spilled

on the ground or into the water.

that is why every actuator we sell is manufactured to exceed

standards set forth by the American Petroleum Institute (API) in

specification 6A, Latest Edition and why Array’s quality systems

and the quality systems of all of our suppliers are certified by

API and/or the International standards organization (Iso).

It is also why we spend so much time working closely with our

customers and suppliers to continuously improve the quality

of our actuators, as well as the efficiency of our systems –

because we recognize that the quality of our products can

positively impact the quality of our environment.

It is our primary concern and motivation.

mODEL APD PNEUmATIC DIAPHRAGm ACTUATORFOR API 6A WELLHEAD GATE VALVES (SINGLE ACTUATOR APPLICATIONS)

GENERAL DESCRIPTION

the Model APD actuator is a diaphragm type, pneumatically-powered gate valve actuator designed to operate a “fail-closed” or “fail-open” safety valve. It is ideally suited for wellhead safety valve applications, flow lines, header valves and gathering lines. It can also be used for casing relief valve and storage valve applications.

the Model APD actuator is lightweight, easy to maintain and engineered to ensure years of trouble-free service in the harshest of environments and operating conditions on land or off-shore.

the Model APD actuator can be delivered as an actuated valve assembly ready to be placed in service or as an actuated bonnet assembly ready to mount on another manufacturer’s valve.

(shown with typical bonnet assembly)

FEATURES AND BENEFITS

Longer Top Shaft Seal Life: PolyPak™ seals are used for top shaft dynamic sealing applications. these seals are protected from accumulation of dirt and debris by a durable wiper ring. these two features provide long seal life and minimal maintenance.

Ease of Maintenance: top shaft seals are easily replaced in the field by simply removing a retainer ring. Disassembly of the actuator or upper housing is not required for seal replacement.

Improved Corrosion Control: All non-stainless components are coated with Xylan and Polyester tGIc providing resistance against the corrosive effect of harsh environments.

Over-pressurization Protection: A pressure relief device on the actuator top case protects personnel from over-pressurization of the actuator assembly. It is located for easy field inspection and replacement.

Confirmation of Bonnet Stem / Back Seat Seal Integrity: the bonnet is designed with a test fitting below the bonnet seals. this test fitting provides for verification of the bonnet stem metal to metal backseat pressure sealing integrity.

Visual Confirmation of Bonnet Packing Integrity: A tattletale port located above the bonnet packing seals provides visual confirmation of the packing integrity. the Bonnet is provided with a port that can be tubed to a containment vessel to present escape of fugitive emissions into the atmosphere.

Modular Design: tandem boosters (additional diaphragm actuators) can be mounted in the factory or the field to provide higher actuation force.

Multiple Safeguards Against Well Fluids Contamination: the bonnet incorporates multiple safeguards against the invasion of well fluids into the actuator housing. these safeguards are:

• Metal to metal back seat/stem seal

• Multiple Polypak™ bonnet stem seals

• Packing integrity port

• secondary backup seals utilize o-rings

Personnel Safety: Locking screws below the bonnet ring prevent free rotation of the actuator. this guards against personnel injury should the actuator be used as a step during field service operations.
