Introducing Parker 7321B/7322B Series Water Valves General Description

Parker 7321B/7322B are diaphragm pilot operated solenoid valves and require a minimum differential pressure to operate-
This serie is available in both Normally Closed and Normally Open function: 7321B Serie is a Normally Closed family (closed when de-energised), 7322B Serie is the Normally Open family (Open when de-energised)- Material Speci- cations
Valve body: CW617N UNI EN 12165:98 Forged Brass Enclosing tube: AISI 304 stainless steel Plunger: AISI 430F St- Steel Spring: Seals: Shading ring: AISI 302 St- Steel NBR (Buna N) - EPDM FKM (Viton) Copper

Installation

The valves can be mounted in any position- It is however recommended to install them with the coil in vertical position above the body-

Media

These valves have been developed to achieve the best performances for water, steam, light oils (up to 2°E)- Therefore these valves are not usable with gas and air- We recommend to choose NBR versions for plumbing mkt (max- temp- 90°C), FKM version for water/light oils control applications up to 140°C, EPDM version for superheated water and steam (up to 140°C)

Electrical Parts

A wide range of electrical parts are available for 7321B/7322B Series- The complete offer of electrical parts is shown at pages 18 to 21-
Please consult factory in case you need to verify the compatibility of 7321B/7322B Series with alternative ranges of paper FCDE coils not inclused in this catalogue- Please consult also the "How to Order" section at page 22 to select the product con- guration which - ts your application requirements-

Available Options

Manual Control

Parker 7321B Serie (NC version only) can be ordered with Manual control option- A manual control is used to operate the valve without connecting the coil-
The control consists in a slotted-head screw for a screwdriver and has two possible positions:
Closed: The letter "C" is in the upper position of the screw head (- g- 1,2) Open: The letter "A" is in the upper position of the screw head (- g- 1,2)
Standing in its closed position, the valve operates normally when coil is energised/de-energised- Manual and speed control are standard on 2 - " and 3" versions-

Speed Control Option (Anti-Water Hammer Control)

Parker 7321B Serie (NC version only) can be ordered with Speed control option- The closure time of certain types can be changed by means of the adjusting screw- The latter, by acting as a throttle on the inlet equalisation (pilot) hole of the valve, slows down the closure speed of the valve, thus reducing the water hammer effect-
The regulation range is as follows:
Screw fully open: Max- closure speed Screw fully closed: Valve always open

Please consult diagrams at page 6 of this catalogue to - nd details about shut-off response time with speed control option-
