TOLBOOM VALVE customers can rely on more than 40 years experience in the ball valve industry, and more than 30 years experience in design and manufacturing of Non-Contact Ball Valves.

TOLBOOM VALVE is technically and commercially the best choice for Non-Contact rising stem and Metal to Metal seated ball valves.

TOLBOOM VALVE is based on a combination of a turning and linear movement of the closing member, resulting in friction free turning and sealing, and a very low stem torque.

Lower price

The compact design results in lower production cost

Less maintanance

Due to longer durability and higher reliability compared to other ball valves

Lower operation cost

Cost of required actuators will be significant lower, due to the low stem torque

Usage of standard actuators

Use of standard quarter turn available actuators

Less energy

Save up to 70% energy to operate the Tolboom Valve

Build-in dimensions

The build-in dimensions of a Tolboom Valve is 70% smaller (height) compared to a Rising Stem Ball Valve

Commercial Features

Fresh ideas to be multifaceted

The compact design of the valve results in lower production cost, and LOWER PRICES.

Cost of required actuators will be significant lower, due the low stem torque, and the use of standard quarter turn available actuators.

Environmental Features

There is only one Mother Earth, Let’s treat her with respect

The Environment is a high priority of the Tolboom Valve Company.

The Tolboom Valve only requires 40% of the normal operational energy consumption compared to Rising Stem and Metal to Metal seated ball valves. An energy consumption reduction of 60%.

The compact design requires less material and significantly less energy to produce.

Adjustable Stem sealing prevents leakage to the environment.

Design Features

Only 90 degree stem turning to open or close the valve.

  • Compact build-in dimensions. Not larger than a standard API 6D Top-Entry valve.
  • Top entry design for in-line maintenance and inspection.
  • Sealing force between seat and ball can be exercised outside the valve.
  • Mechanical closing member is out of the flow line.
  • Single seat design, no thermal expansion danger.
  • Self-cleaning and sealing-area due to the immediate 360 degrees flow velocity when opening or closing the valve.
  • Stationary seat.
  • Mechanically energized sealing.
  • Suitable for bi-directional flow.
  • Small engineered distance between ball and seat, avoiding bulky solids being jammed.
  • Reversed bottom and top trunnion, to avoid pollution of the trunnions.
  • Quarter turn stem design, suitable for standard available actuators.
  • Blow-out proof stem.
  • Adjustable stem packing, while valve is in service. Optional with life load Belleville springs.
  • Long lifetime.
  • Metal to Metal as well as Soft Seated available.
