Our take on the Bonomi 8P0135LF Ball Valve, 253N LF Direct Mount, 2-Way, Lead-Free Brass, NPT, Full Port with Double Acting Actuator

The Bonomi 8P0135LF is a lead-free brass ball valve with a factory-mounted double-acting pneumatic actuator, built for on/off control of water, air and other compatible media in industrial and commercial piping. Its full-port design keeps pressure drop low, the stainless steel ball and stem resist wear, and the PTFE seats handle a wide temperature range. The 253N direct-mount actuator runs on 80 to 116 psi supply air and drives the valve open and closed, so it needs air on one side to hold position rather than a spring return. It suits OEM skids, process lines and building services where automatic shutoff is needed; against plastic-bodied or standard-port actuated valves it offers higher pressure capability and better flow, at the cost of needing a reliable air supply.

Pros
  • Lead-free brass body with stainless steel ball and stem
  • Full port for low pressure drop and high flow
  • 600 psi WOG rating handles demanding lines
  • Direct-mount 253N actuator simplifies installation
  • Made in Italy with Bonomi's valve reputation
Cons
  • Double-acting actuator needs air to hold either position
  • Requires 80 to 116 psi supply air and solenoid piloting
  • No spring return means no fail-safe position on air loss
  • NPT threaded ends limit it to threaded piping systems

Questions and answers

What does double acting mean on this valve?
Air pressure drives the valve both open and closed. It has no spring, so it stays where it is put and needs air on the opposite port to move back. If air is lost, the valve holds its last position.
What air pressure does the actuator need?
The 253N actuator takes a minimum of 80 psi and a maximum of 116 psi supply air. Below the minimum it may not shift reliably; above the maximum you risk damaging the actuator seals.
Is this valve safe for drinking water?
The body is lead-free brass and the ball and stem are stainless steel, which suits potable water service. Check that your local code accepts the PTFE seats and the specific approval markings on the valve for your application.
What is the difference between full port and standard port?
Full port means the bore matches the pipe size, so flow is close to unrestricted and pressure drop is low. Standard-port valves are more restrictive and better suited to lines where flow capacity is not critical.
Can I use it with a solenoid valve and positioner?
Yes. A solenoid valve controls the pilot air to the actuator, and a switch box or positioner can be added for feedback or modulating control. The direct-mount pad accepts standard NAMUR accessories.
What media can it handle?
It is rated for water, oil and gas service up to 600 psi WOG, with PTFE seats covering a wide temperature range. Avoid media that attack brass, PTFE or stainless steel, and check the temperature rating for your line.
