SOLENOID VALVE APPLICATIONS


DO YOU OFFER AUTOMATIC CONDENSATE DRAIN KITS FOR PNEUMATIC SYSTEMS?
Yes, our H2O-GO products are intended to automatically drain condensate from air systems. The automatic control is a DIN timer (T4510) which can be adjusted for as much as 45 minutes off and up to 10 seconds on. A normally closed solenoid valve with DIN housing is energized by the timer. A 6 foot cord with 110ac plug (C4010-GRN1) can provide power from a standard wall outlet. And a combination ball valve/strainer protects the valve from entrained solids and isolates the valve for maintenance.
​H2O-GO Compressor Drain Kit - Typical part numbers:
1/4" NPT -- K4510S30Y02BD5
3/8" NPT -- K4510S30Y02CD5
1/2" NPT -- K4510S30Y02DG4

Larger pipe sizes also available. Contact your distributor or the region office for more information.

DO YOUR SOLENOID VALVES MEET THE REQUIREMENTS OF THE 2014 U.S. SAFE DRINKING WATER ACT?

Yes. GC Valves manufactures stainless steel solenoid valves from 1/8” to 2” NPT that do not contain lead. 

We also manufacture solenoid valves with Noryl bodies from 3/8” to 1” that do not contain lead. Many of these

valves also carry NSF 61 certification for “Drinking Water System Components”.

"Lead free" legislation in the U.S. relates to any pipe, pipe or plumbing fitting, or fixture intended to convey or dispense water for drinking or cooking. For these products, "lead free" means not more than a weighted average lead content of 0.25 percent.

California and Vermont had already enacted "lead
free" legislation. The U.S. Safe Drinking Water Act made this a national requirement in January 2014.

SOLENOID VALVE ELECTRICAL INFORMATION


SENSIBLE PRECAUTIONS FOR ELECTRICAL & CONTROL

Solenoid valves can be economical solutions to flow control requirements.  And they are easy to maintain.  But any electro-mechanical device has limitations.

Here are a few choices that might add to your comfort level when applying solenoid valves:

1 -- specify DIN coils and connectors to simplify assembly and reduce installation time

2 -- investigate the use of rectified coils if "ac hum" is a concern, especially in residential installations

3-- consider DIN electrical connectors with integral surge suppression to protect control electronics

4 -- use lighted DIN connectors to simplify troubleshooting

5 -- evaluate magnetic latching coils for battery operation or when heat generated by the solenoid valve coil is a concern.

And be sure to ask your distributor or region manager about the availability of manual override if valve operation is required when power is interrupted.


GC VALVES HOUSING OPTIONS

Solenoid valve coils and housings offer a variety
of options for electrical connections.  In addition to lead wires, CFA and GC Valves offer:

  • 1/2" conduit housings, including several junction boxes
  • DIN (European tab) coil/housings and connectors
  • Explosion proof NEMA 7 housings
  • Submersible housings
  • Metallic housings
  • Fully encapsulated NEMA 4/4X coils/housings.

We even have 120vac cords with standard 2-prong or 3-prong wall plugs.  240 volt, too.


ELECTRICAL HOUSING CODES

Here are the GC Valves Housing
Codes (position 5 in the part number)

  • A – Metal ½” Conduit with 24” leads
  • B – Metal Grommet with 24” leads
  • F – DIN Housing with C-4010 DIN Connector
  • G – Fully Encapsulated ½” Conduit with 24” leads
  • P – Open Frame with 24” leads
  • S – Metal Junction Box
  • U – Round Junction Box with 2 ½” Conduit Knockouts

  • X – Explosion Proof Metal ½” Conduit with 24” leads (NEMA 4 and NEMA 7)
  • Y – Fully Encapsulated DIN Housing

36” and 48” leads are also available.


EXPLOSION PROOF HOUSINGS

Most solenoid valves from GC Valves are available with explosion proof housings:  they are rated NEMA 7, Class I, Groups C & D; Class II, Groups E, F, & G, Division 1 and 2.
These classifications refer to explosive mixtures that may be in the atmosphere around the valve, not the gases etc. that flow through the valve.  The explosion proof housing is designed to prevent an explosion of dust or gases in the atmosphere outside of the valve.

GC VALVES INCREASES
FLEXIBILITY IN 24VAC SOLENOID VALVES

 Responding to customer requests, GC Valves has standardized on a more widely applicable 24vac coil design. 

24vac valves using S3 and S4 coils  are now shipping with voltage code “24”:  24V/60HZ  24V/50HZ.   For no difference in operating pressures, the “24” coil cuts inventory requirements for companies that provide
products to both 60HZ and 50HZ countries.  

 

The S3 and S4 coils are used on S20, S21, S30, S31, S33, and S40 solenoid valves (and related “H” or “NS” versions)
with all housings.  Voltage code “01” coils (24V 60HZ) that were replaced by the “24” are still available as a special order.

 

SHADING RINGS FOR AC VOLTAGES

Solenoid valves that operate on AC power required a non-magnetic element in the plunger head.  We typically build brass and Noryl bodied valves with copper shading rings; stainless steel valves normally have a silver shading ring.  The shading ring is intended to prevent the buzz or chatter caused by the zero voltage cross-over point in the AC cycle.  DC voltage solenoid valves do not require the shading ring, which is why the entire operator must be replaced when changing a DC valve over to AC power.

 

DIN LIGHTED CONNECTORS

Most of our solenoid valves can be built with “International tab” or DIN coils. This world-wide standard allows many options for wiring and built-in electronics. Among the most popular is the lighted connector which incorporates an LED to indicate that power is supplied to the DIN connector.  It can be a valuable tool during factory test, field installation, and trouble-shooting.

 

 

SOLENOID VALVE DESIGN & OPERATION


SENSIBLE PRECAUTIONS FOR SOLENOID VALVE USERS
​Solenoid valves are your fastest acting option when controlling flow, they can be repaired in-line (without breaking plumbing connections in most designs), and they can be less costly than other electrically operated valves. 
But there are a few measures that can increase your satisfaction with solenoid valves: 
1 -- install strainers or filters to prevent foreign materials from entering the valve and interfering with operation
2 – avoid teflon tape:  those stringy leftover pieces can travel downstream and hang up in the valve
​3 – use pipe dope sparingly: globs of it in the line can affect solenoid valves and other control elements
4 -- add check valves if it is important to prevent back flow through the solenoid valve
5 -- plumb solenoid valves in series (double-block) when leakage is unacceptable
6 -- add manual override to allow operation when power is off
​7 -- ask for a plated operator to protect special grades of stainless steel from corrosion.
​And be sure to let you distributor or region manager know about everything in the line fluid:  additives in air, water or other fluids can change the soft-seal requirements.


SLOW CLOSING VALVES

GC Valves offers slow closing designs in the most common sizes. Choose our “4” brass body to help reduce water hammer in 3/8” through 2” NPT. Stainless Steel versions are also available in the larger pipe sizes.


FAQ:  GRAVITY FEED
Why do I only get a trickle of water in my water tank drain?  The diaphragm valve seems to work fine with compressed air?
ANSWER:  Piloted Diaphragm solenoid valves typically require a minimum pressure of 4 to 10 psi to fully open. A water tank with 24" of water creates a pressure differential of less than 1 psi. You will need to find a Zero Pressure Differential design.  See below


ZERO PRESSURE DIFFERENTIAL DESIGNS

Many GC Valves solenoid valve designs are intended for tower and tank drains, closed loop systems and other low pressure applications where there may be little or no pressure differential to assist the valve in fully opening. 

  • 3/8” to 1-1/2” NPT: S20
  • 1” to 2” NPT: S27
  • ¼” to ½” NPT: S40 and H40
  • 1/8” to 3/8” NPT:  S30 and S31
