Valve Bodies, Components and Assemblies

The high quality V-Series two-way and three-way globe valves are manufactured to exact specifications and are designed to provide years of reliable service

The high quality V-Series two-way and three-way globe valves are manufactured to exact specifications and are designed to provide years of reliable service. The assemblies are designed for heating/cooling applications using steam, water, glycol or other non-corrosive fluids. The V-Series assemblies should not be used with combustible fluids such as natural gas. The V-Series products are available as complete assemblies but most users purchase the bodies, actuators and linkages separately for convenient local assembly.

 

Three-way Valve Bodies

 

 

 

Valve bodies are available in three-way configuration as mixing and diverting valves. Sizes range from 1/2" to 6" pipe size or 5/8" O.D. SAE 45º copper tube.

 

 

 

Selecting the proper valve body requires the following data:

◾Fluid type

◾Fluid temperature

◾Port size (Cv rating)

 

 

 

Selecting the proper port size requires the following data:

◾Inlet pressure

◾Required flow rate in either GPM (liquid) or lbs/hr (steam).

 

 

 

If the customer is using on-off control, just select the valve body with the largest port size in the requested pipe size. Remember the following rule when sizing the valve for proportional control. “At least one-half of the available pressure must drop across the valve body when the valve is fully open.” An oversized valve body will result in very nonlinear control action. It is better to have too small of a valve body than too large of one

Actuators

 

Linear stroke electric and rotary stroke box-style actuators are suitable for use with our valve bodies. See the Actuators section of this website or the Eurotherm Product Catalog for complete details.

 

 

 

 

 

 

 

 

 

IDEAL FOR:

 

◾Heating and cooling applications for non-corrosive fluids

 

 

◾Steam and hot water flow control

 

 

FEATURES:

 

◾Complete valve assemblies or components available

 

 

◾Electric actuators and linkages

 

 

◾Two-way flow and three-way mixing and diverting valves

 

 

◾1/2" to 6" valve sizes

 

 

Linkage Kits

 

Most actuators require mechanical linkage kits specifically designed to couple them to the valve bodies. Several varieties of linkage kits are available to match the valve bodies to our range of actuators for various applications. Complete assembly instructions are supplied with each kit.

 

 

 

 

 

 

 

 

Complete Valve Assemblies

 

Complete valve assemblies consist of a valve body and selected actuator, coupled by a matching linkage kit. Usually customers order the body, actuator and linkage kit individually and easily assemble their own valve assemblies. However, among the many possible combinations of bodies, actuators and linkages, there are several standard ones that may be ordered from the factory as completely pre-assembled valve assemblies.

 

 

Valve Model Code

 

Refer to the sample valve model code below for the format to use when specifying model numbers. When valve bodies only are being specified, the Control Form field will always be specified as "VB" and the Actuator field will always be "000". When a complete factory assembled valve is being specified, the Control Form field will change to one of five options (VA, VC, VF, VP, or VS), depending upon the type of control action delivered by the selected actuator. The actuator and matching linkage for this Control Form are then identified in the Actuator field by replacing the "000" with a prescribed three-digit code identifier for the selected combination. This three-digit code is only used when specifying available factory assembled valves. A description of available 3-digit codes for the Actuator field, which specifies factory assembled valves is given in the Valve Assembly Tables.
