Key Features & Benefits
Basic Design Standard : ASME B16.34
Variety of Trim Type
Various trim designs provide a wide range of flow control, noise attenuation, and Anti-Cavitation control.
Low Emissions Packing and Emissions Free
Low emissions packing is available to meet environmental safety and emissions control
requirements, and bellows seals are available to meet zero emissions requirements.
Suitable for Low Differential Pressure Systems
Suited for applications where the pressure differential across the valve is relatively low,
these valves are efficient in systems requiring fine flow adjustments.
Tight Shutoff
Tight shutoff capability prevents fluid leakage, which enhances system safety and
reduces fluid loss.
Ease of Maintenance
The quick change trim design makes maintenance easy, and component replacement or repairs are relatively straightforward.
This minimizes downtime and reduces long-term maintenance costs.

Contoured Trim
P - Port
The trim is unbalanced. By plug throttling, using parabolic contoured plugs in globe control
valves provides precise flow control and high-pressure recovery, making it effective for
various industrial processes.
The design of these plugs maximizes valve performance and
allows for flexible response to diverse control requirements.
Micro Flow Trim
V-Notch Plug
V-notch trim features a design with a V-shaped cut on the valve plug. This design allows
for more precise control of fluid flow especially very small flow rates must be accurately
controlled, making it a highly effective solution for applications requiring fine and stable
flow control.
Due to its design and operational benefits, it is the preferred choice in many
industries where accurate flow regulation is essential for process efficiency and product
quality.
Anti-Cavitation Trim
Multi-Step Plug
Multi-step trim is a technology designed to handle liquids pressure drop in a series by dividing the pressure reduction into multiple stages of labyrinth grooves.
By gradually reducing the pressure through multiple steps, it effectively minimizes cavitation, noise, and erosion.
The characteristics of this design provide stable and efficient control in various applications with high-pressure differentials, reducing noise and vibration, and enhancing the overall performance of the system.
