Reliable Side Entry Ball Valve

A side entry ball valve is a type of valve where the ball is assembled from the inner part, typically within a two- or three-piece body. The components are joined using studs or bolts, similar to how 2 flange pieces are connected. These valves are made from forged metal, with each part of the body forged separately before being assembled.
 
This construction method helps minimize defects often associated with casted valves. The assembly process is straightforward, as the components align easily. Side entry ball valves are among the most commonly used ball valves.
 
A side entry ball valve is designed to achieve high performance and features a sturdy design that complies with international standards. These valves contain either metal, soft, or composite seats, which can be configured with a single or double piston effect to achieve double block and bleed functionality in both open and closed positions.
 
Manufacturers typically produce these valves using forgings and independent bellows or spring-loaded floating seats that maintain constant contact with the ball. This design makes side entry ball valves a preferred choice for various demanding applications, such as cryogenic services, low emission environments, high-temperature operations, crude oil and natural gas processing, transmission lines, measuring stations, compression, reinjection, and pumping units.

How Does a Side Entry Ball Valve Work?

Side entry ball valves operate using a spherical closing unit that controls the on/off flow of fluid. This spherical unit has a bore through its center. When the valve is in the open position, the bore aligns with the direction of the pipeline, allowing fluid to pass through. Rotating the valve by 90 degrees moves the bore perpendicular to the flow path, closing the valve and preventing fluid flow.
 
The most common design inside a side entry ball valve is the two-way design, which allows fluid to flow linearly from the entry to the exit. These valves are known for their long service life and reliable sealing, even when the valve remains unused for extended periods. Additionally, side entry ball valves tolerate contaminated fluids better than many other valve types.
 
While these valves can be used to control fluid flow rates, this application is less common because achieving precise flow control can be challenging with this type of valve.

Types of Side Entry Ball Valves

Soft Seated Side Entry Ball Valve
This type of side entry ball valve is classified based on the seat material used. In a soft seated side entry ball valve, a non-metallic, soft material is utilized, covering a wide range of applications. These valves are typically made from thermoplastic materials such as NBR and PTFE.
 
However, they can be easily damaged when exposed to abrasive media, high temperatures, or high-pressure fluids. In this design, elastomeric or thermoplastic seats are fixed within a metallic seat ring or holder, providing the soft seating action in the valve.
 
  • Provides effective sealing.
  • Operates within limited temperature ranges.
  • More cost-effective compared to metallic seated valves.
  • Uses soft seat materials like nylon, PTFE, Devlon, and PEEK.
  • Not recommended for use in dirty services to avoid damage.
Metal Seated Side Entry Ball Valve
These valves are constructed from metallic materials such as 316 SS and Monel. Metal seated side entry ball valves are recognized for their resistance to jamming, tight shut-off capabilities, wear resistance, and durability under a wide range of temperatures. They also offer good corrosion resistance and stable performance under pressure.
 
  • Direct metallic contact between the ball and seat ring.
  • Suitable for abrasive applications and environments where soft-seated valves might be damaged by temperature.
  • Can tolerate leakages according to ISO 5208 rate D.
  • The contact surfaces between the seat and ball are hardened to resist wear and scratching from solid particles in the fluid.
  • Metallic seats are less likely to deform under pressure compared to soft seats.
Trunnion Mounted Side Entry Ball Valve
The main characteristics of this type of side entry ball valve include:
 
  • The valve seat is spring-loaded against the ball, providing a reliable seal at low pressures.
  • The ball is mounted in position using a trunnion and stem, supported by bearings in the valve body.
  • Unlike floating side entry ball valves, the trunnion mounted design prevents the ball from shifting. Instead, line pressure pushes the upstream seat against the ball, creating a seal.
  • These valves are typically used for higher pressure ratings and larger sizes.
  • The area exposed to pressure is small, resulting in a lower force exerted on the ball, which reduces friction and allows for a smaller gearbox or actuator.
  • Trunnion mounted side entry ball valves are designed with self-relieving seats.
Three-Piece Side Entry Ball Valve
This side entry ball valve consists of 1 center piece and 2 end pieces. It is primarily designed for online maintenance. When the body bolts are removed, except for one, the body can be swung away using the last bolt as a fulcrum, allowing for easy maintenance or installation. This design helps reduce the time required for maintenance.
Floating Side Entry Ball Valve
Also known as seat-supported side entry ball valves, these valves have several distinctive features:
 
  • The ball is not rigidly fixed on the rotational axis but floats freely between seat rings.
  • In the closed position, fluid pressure pushes the ball against the seat, enhancing the seal at the downstream end of the valve.
  • Some designs also include spring-loaded seats.
  • Floating side entry ball valves require higher operating torque.
  • These valves are more economical to manufacture.
Two-Piece Side Entry Ball Valve
This type of side entry ball valve is made into 2 pieces, with the ball held in position by a stud. It can feature either a reduced bore or full bore design.

Components of a Side Entry Ball Valve

Valve Body

The valve body is the primary component of the side entry ball valve, housing all the internal parts responsible for controlling the on and off operations of the valve.

Rotary Ball

The rotary ball is a spherical component with a center hole through which fluid flows. This hole, aligned along one axis, connects the valve’s inlet and outlet, distinguishing ball valves from other valve types.

Power Source​

The power source for a side entry ball valve can be either manual or automatic. Manual actuation is achieved through handles and levers, which the operator uses to control the valve’s on and off positions. Automatic actuators use pneumatic, electric, or hydraulic power sources to rotate the stem and ball, thereby controlling the flow.

Seats

Seats are discs positioned between the valve body and the ball. They provide a seal between these components and 
support the ball during operation.

Stem

The stem connects the rotary ball to the external control mechanism, allowing the operator to control the 
direction of the ball.

Packing

Packing is a seal placed around the stem to prevent fluid from escaping the valve.

Bonnet

The bonnet is the component that encloses the packing and stem, providing a secure housing for these parts.
