Description

Introduction

BP series actuators adopt the classical scotch yoke mechanism design, which can output maximum torque at both ends of the stroke, available for Ball Valves, Butterfly Valves, Plug Valves and all the 90° rotation valves, widely applicable to the chemical industry, food & beverage, metallurgy, offshore platform, pharmaceuticals, energy, paper, textile and other industries.

The Ambient Temperature

Standard actuator: -20°C to +80°C

Low temperature actuator: -40°C to +80°C

High temperature actuator: -20°C to +120°C

Operating Pressure

Pneumatic actuator:3~10 Bar

Hydraulic actuator: 50~250 Bar

Product Feature

1.Totally Enclosed Housing Design

Totally enclosed weatherproof centre body fabricated in carbon steel or Centre body has been designed totally enclosed, weatherproof housing fabricated in carbon steel or welding material provide an excellent strength.

2.Standard Mounting Flange

The mounting flange accord with the ISO5211 standard, accessories mounting size accord with NAMUR VDI/VDE 3845, which is convenient for mounting accessories such as Limit Switch box, Positioner and so on.

3.Wear Resistant

The guide rod and piston rod with advanced surface treatment combined with self-lubricating bearings, which provides superior wear resistance and extends the life of all sliding components.

4.Water Ingress Protected

Sealing gaskets are fitted in the joint between body, cap, pneumatic cylinder and so on, which prevent from water ingress.

5.Corrosion Resistant

BP series pneumatic actuators coated with over 3 layers of protective coating, which can meet the requirements of the petrochemical and coastal environment.

6.Self-lubricating

BP series pneumatic actuator has been designed to be completely self-lubricating, which ensure maximum wear resistance and long cycle life. No need of lubrication.

7.Modular construction Design

BP series pneumatic actuator has a efficient and interchangeable modular construction design, including centre body , pneumatic cylinder, spring cartridge, hydraulic cylinder, override modular and so on. Modular construction and stocking of components by THEOBORN facilitates quick delivery time.

8.Safe Spring Module

To ensure the safety of personnel during installation and maintenance, the spring cartridge module can be only removed from the axes of the pneumatic cylinder module, which avoids the damage to the working people and pneumatic devices.

9.Manual Override

Available with declutchable manual override and hydraulic manual override.

10.Minimum Maintenance

BP series pneumatic actuator is built to provide long and efficient service with minimum maintenance.

Structure Feature

1.Steel Guide Bar

Hard chrome plated alloy steel guide bar provides optimal support of the transverse loads.

2.Slider Block

Aluminum bronze slider blocks and high frequency quenching steel shaft pin minimize contact stress and ensure high cycle life.

3.Cylinder

Electroless nickel plated and polished cylinder for corrosion resistance and minimal friction.

4.Guide Ring

Made from low friction, long-life compound material, to avoid the direct contact between metals, the maintenance and replacement are easy and convenient.

5.Spring

High strength alloy steel spring to maintain consistent torque output and promote high cycle life performance.

6.Travel Adjustment

Bi-directional travel stops allows 90°±5°

travel adjustment, which make

the valve be in the

best position.
