Detail Low Flow Control Valve
Masoneilan 28000 Series Varipak* Low Flow Control Valve
The Masoneilan 28000 Series Varipak globe-style control valve provides excellent throttling control performance in micro-flow or very low capacity applications. It includes an integrated actuator design with an external flow adjustment feature providing customers with a unique flexibility to optimize their process in-situ.
Features & Benefits:
* Precise micro-flow control for improved process efficiency
* Field adjustable actuator allows customers to change valve flow capacity without removing or disassembling the valve saving time and avoiding valve over-sizing which can result in accelerated trim wear
* Versatile design options built on a common platform minimizes overall inventory and training requirements
* Compact and modular valve design offers excellent throttling control for micro-flow applications
* Integrated compact actuator design offers a standard flow-capacity adjustment feature for inline versatility
Application:
The Masoneilan 28000 Series Varipak control valve is designed to handle low flow control applications requiring precision and accuracy. The globe-style construction is suited to meet the following types of service conditions and operating requirements:
* Low to micro-flow applications
* Moderate to high pressure drops
* Tight shutoff seat leakage
* Cavitating & flashing liquid applications
* Low emissions and zero leakage options
* High pressure operating conditions
* Low temperature and cryogenic applications
Design:
The Masoneilan 28000 Series Varipak is a compact control valve assembly with an integrated actuator and positioner design. Customers can easily adjust the valve flow capacity to meet changing process requirements.
* External flow adjustment and tuning feature to optimize process efficiency
* Bellows seal construction provides zero leakage performance for toxic or lethal fluid applications
* High pressure anti-cavitation trim option effectively prevents potential valve damage
