GOST Solenoid Valve Order For Extreme Ambient Temperatures

(Posted 01/08/2014 11:24)

It's not often that we at Red Dragon like to speak about cold arctic conditions, but a recent large order changed all that.

GOST R Solenoid Valves

After careful analysis, and close collaboration with our customer, Red Dragon delivered a large quantity of Solenoid Valves, all certified to GOST R Standards. Our customer needed a fast solution where the ambient temperature was very low. Our GOST R solenoid valves are rated to amb. -60C to +60C. Our manufacturer NADI gauarantee the working of the valve at these extreme temperatures.

High Dependency Solution

We supplied our model D13, a five way single solenoid, with stainless steel body and HNBR seals. The D03 has a compact design with a large opening in the coil housing to aid difficult site electrical installations, where extreme environments can cause issues.

IP67 rated Waterproof Housing for High Pressure Solenoid Valves

(Posted 21/07/2014 12:25)

Nadi Srl, the Italian solenoid valve manufacturer has just supplied a large quantity of solenoid valves for a special project. The order was delivered on time, even though the valve body had to undergo a special treatment.

Valve Technology

The L20 series from NADI is a pilot piston solenoid valve, with the special feature of working with high pressure, yet allowing a high flow of liquids due to the 8.7mm internal orifice. All internal moving parts are available as spare parts, allowing users to maintain the valves in the field.

Waterproof Housing

Due to the application, the valve could encounter high amounts of water spray from the plant. The L20s has an IP67 solenoid coil housing, ideal for preventing ingress of water. Electrical power to the solenoid is via a female threaded entry, which can be either M20 or 1/2" NPT.

Cost Effective Solution

The L20s uses the latest CNC technology for precision machining, allowing for a cost effective valve solution that is both technically and commercially viable.

New Manual Reset Solenoid Valve for Namur Compatible Actuators

(Posted 15/07/2014 10:09)

Nadi Srl, the Italian solenoid valve manufacturer has just announced a new variant of the established D50 series Namur mounted solenoid 3/2-5/2 selectable function pilot valve. The new G50 series pictured here incorporates the same body and innovative function selection seal arrangement as the D50 with the addition of manual reset for use where fail safe operation of the actuator is required in the event of supply removal. This means that the G50 valve can be fitted to double acting actuators with the 5/2 configuration and single acting actuators as either 3/2 normally closed or 3/2 normally open just by changing the orientation of two seals. This gives excellent flexibility in application and reduces the need to stock multiple variants for production or maintenance spares.

The Namur interface international standard allows all manufacturers to produce interchangeable solenoid valves to mate directly to the actuator, removing the need for direct piping and reducing the operating time. Now we can offer the same interchangeability as the auto reset valve but with the manual reset function which previously would have required an inline 3/2 valve to be hard piped to the actuator.

The G50 is available with the same options as the existing D50 range: Brass or 316 stainless steel bodies with standard IP65 coils, coils with IP67 terminal housings or IP67 ATEX Exd certified versions. GOST certification is also an option and ambient temperature capability of -60°C to +60°C.

New All-In-One dew point monitor for refrigeration dryer

(Posted 25/06/2014 09:25)

Maintaining the quality of compressed air is vital to efficient operation by preventing corrosion related and process contamination issues.

CS- iTEC GmbH offers with the newly developed CS 305 a measuring device for dew point monitoring that kicks in alarm indications when drying values are not within the desired range which is ideal for use with refrigerant dryers.

The All-In-One dew point monitor serves as a measuring and display device. The connection to the compressed air network is via a 6mm quick connect and corresponding connecting hose. The entire measuring unit is integrated together with the display in a rugged housing (IP 65) and is available both as a panel variant or as a wall-mounted housing. Two alarm levels can be programmed (pre and main alarm), serving as optical indications or separate relay outputs. The dew point meter allows a simple and inexpensive dew point monitoring.

ATEX Stainless Steel QEV range expands up to 1”

(Posted 7/02/2014 11:10)

Now available from stock at Red Dragon, pneumatic Quick Exhaust Valves (QEV) manufactured in 316L stainless steel to suit the harshest environment in sizes up to 1"NPT. The Sitecna VSR range has recently added two new sizes, 3/4" and 1" to complement the existing 1/4" and 1/2" versions.

Designed to offer high flow capacity for linear or quarter turn pneumatic valve actuators, these new sizes allow the rapid removal of large volumes of air to maximise closing speeds for Emergency Shut Down (ESD), failsafe or high speed valve operators.

The robust 316L stainless steel construction (NACE MR01-75) and choice of elastomer options for operating at temperatures down to -40deg C are complemented by ATEX certification for use in hazardous areas and GOST certification demanded for applications in the Russian Federation.

For more details on these Quick Exhaust Valves please call us on +44 (0)1443 772500 or visit www.sitecna.co.uk
