Thank you for the replies. Some clarifications.
1. The valve is used in Railway pantograph and cannot be relocated anywhere else. Its is exposed to the elements 24x7.
2. This valve controls the maximum height that the panto can reach.
I've tried to educate the customer but then again it...
Hi,
Does the IP65 protection class apply to Non - electrical equipment too?
I have a Pure pneumatic valve (3/2 single plunger operated) which has no electrical component. Our customer wants it IP65 rated. There is very little room for modification to make it water or dust tight (actually we...
Few points to clarify now. The design is changed. We've now incorporated two gussets, M6 nuts (Cheese head with Allen nuts) 8 nos for each surface, more number of holes for mounting on the table. Further, the thread will be only on one mating part with the other having a through hole and a...
Thank all members for your suggestions. Some clarifications.
1. The General Design is as given below.
2. The vibration test is done through an external lab and the dimensions of the bench are as follows.

3. I've dropped the idea of welded plates based on your...
Hello,
I am aware that there are threads which discuss this topic but there are some specifics which i wanted to share in this thread.
1. Specimen : Pneumatic Panel 448x187mm with 3mm R4 bend. Aluminium, 3mm sheet thickness.
2. Test Standard : IEC 61373 HL2
2. Weight 3Kgs (approx.)

Two solutions come to my mind.
1. Use a 5/2 way valve with port 1 connected to a I/P converter. You can set the output pressure using 0-10V /4-20mA signal.
2. Use two 3/2 way valves to connect to port 1 of a 5/2 way valves. These two 3/2 way valves can be connected to different pressures to...
The max speed of a Pneumatic cylinder of 40mm dia (1.5") is roughly 3m/sec. No way you are going to get a speed of 250m/sec using a pneumatic cylinder. Try firing a bullet type projectile.
Any application diagrams?. What is the load (in kgs) that you want to rotate and what is the approx Nm needed?. A Pneumatic cylinder with a rod eye in the piston and a rotary swivel joint to the rear end cover might just rotate a load.
Something to do with Manual Override?. Its a 3 position mid position closed valve. Hence the two dents.
Pneumatic valves have them. I'm not sure about hydraulic ones.
This is what i could get from what i understand of the application. The pressure can be varied from 15 to 5000psi using a 0-10V or a 4-20mA signal. You write a code in the PLC for the scaling between the strain gauge input and the signal output to tune the PID...
Ex d (Flame proof) - Up to Zone 1 : Usually Die cast AL/Iron. Wiring rigged in such a way that the power trips if the lid is opened. Glands have to be Ex d rated too. Max wattage of each component has to taken into account before wiring. Extensively used in lighting.
Ex e (Increased protection...
IS circuit means that the Entity parameters (L/C) of the load (Transmitter) is lower than that of the barrier. So no chance of sparking due to hot working or Shorting. Technically, even the cable's entity parameter has to be considered for the length between the marshaling cabinet and the...
