Some models BH Masoneilan control valves / pressure reducing valves / check valves :

Varipak: precise microflow control valve with compact design and adjustable Cv

• Varipak microflow has a very wide range of capacities (Cv) and precise flow regulation
• With precise and easy adjustment of Cv for small changes in the process without dismantling the control valve or shutting down the process
• It is also possible to convert to other capacities/CVs by simply replacing the plug and seat ring. (Possibility of as many as 74 different CVs with a combination of 8 plugs and 5 seat rings).
• Engineered to withstand high pressure drop and vibration conditions
• Available with many types of trim
• Small and compact
• Easy maintenance

Camflex: highly reliable, compact, cost-effective control valve for a wide range of operating conditions

• Fewer parts means increased reliability, less maintenance and longer service life
• Proven uncomplicated design for over 50 years with many improvements since then. Over 1.2 million Camflex valves installed.
• Good regulation under many different operating conditions
• Reduced friction and wear as the unique eccentric plug moves away from the seat when it opens
• Approximately 50% less space and weight than standard globe control valves
• Possibility to achieve different capacity/flow conditions by only changing the seat ring
• Simple and cost-effective solution for replacing globe control valves with Camflex GR
• Easy maintenance

41005: For demanding conditions such as high pressure, cavitation, flashing, noise and high temperatures with particles in the process media

• Robust cage-guided trim for maximum stability and minimum wear
• Multiple trim designs to meet pressure drop requirements and manage noise, minimizing operating forces while providing a safe and tight shutdown
• Balanced trim design for smaller actuator size reduces space requirements and weight
• Wide temperature range (from cryogenic to steam)

VLOG: valve solutions for demanding operating conditions with high pressure drops and energy management with good operational stability and precision

• Trim to be able to handle e.g. high mass flow rate and high differential pressure. As well as reducing cavitation.
• “VLOG” scalable trim design architecture (e.g. maze effect with channels through many (up to 40) planes/steps and 90 degree turns).
• Tight shut-off and fast opening speeds
• Minimal system noise and vibration for longer service life, lower maintenance costs and reduced risk of downtime

LincolnLog: valve solutions for the most demanding operating conditions through gradual reduction of speed and pressure drop that counteracts cavitation. Resulting in less wear and increased trim life.

• The “LincolnLog” trim design throttles and directs the fluid through a tortuous multi-stage flow path. With notches/steps in the plug design that distribute and equalize pressure drop along the entire axis and length of the plug
• Minimizes damage to control parts such as the plug, cage and seat plug, cage and seat by avoiding exposing them to large reductions in speed or pressure
• Reduces damage from metals, sand or other abrasive particles in the process fluid
• Trim in hardened and resistant materials
• Trim design that reduces vibration
• Can be designed with up to ten stages of pressure reduction with pressure drops up to 8000 psi (550 bar)
• Longer trim life minimizes downtime
