Specifications and configuration
Reference — JSX series water-service options
| Parameter | Documented value / configuration |
|---|---|
| Applicable fluid | Water is included in the manufacturer's fluid/seal selection matrix; the selected coolant and seal still require confirmation. |
| Body material options | Stainless steel (SUS) or brass body ordering options |
| Seal material options | NBR, FKM or EPDM ordering options |
| Port connection options | 1/8, 1/4 and 3/8 in. connections are listed by valve size and orifice; R, NPT and G thread codes are listed. |
| Actuation | Normally closed direct-acting two-port solenoid valve; AC and DC coil codes depend on electrical configuration. |
| Water fluid temperature | 1 to 60 degCConditions: scope: Manual says no freezing; selected seal and actual coolant mixture require review |
| Maximum system pressure not differential | 1.0 MPaConditions: scope: This is maximum system pressure, not the maximum operating differential of every orifice or coil; SMC directs differential selection to the catalog |
Manufacturer series reference. Confirm the exact order code, mating parts and stated conditions for the quoted configuration.
Overview
A direct-acting solenoid valve provides an electrically commanded open/closed point on a suitable water branch. It is a different purchasing object from a manual isolator or proportional flow controller.
Construction and interfaces
The source shows one complete JSX valve with threaded metal body and coil. The ordering matrix separates stainless or brass body, NBR/FKM/EPDM seal, thread and electrical options.
Selection
Choose the exact valve size and orifice for the required flow, differential pressure and supply voltage. Verify the coolant against the selected body and seal rather than relying on water alone.
Configuration options
Listed choices include 1/8, 1/4 and 3/8 in. ports, several thread codes and AC/DC coil forms. These are separate order combinations, not specifications of the pictured sample.
Application limits
The low-resolution original is a series appearance reference only. SMC's direct-operated JSX manual lists water at 1 to 60 °C without freezing and 1.0 MPa maximum system pressure for its stainless/brass-body types. This is not the selected valve's maximum operating differential; the manual directs that selection to the catalog. Actual coolant compatibility remains order-specific.
