Q) What is the difference between a square flange and an angle flange valve?
A) The angle flange valve has a three-degree angle on the flange, and the valve hangs down slightly to improve dumping and drainage. Square flange mounts perfectly square off of the tank.

Q) If my tank is slightly curved how does the valve mount?
A) We offer a mating installation tube to weld into your tank, available in mild, stainless steel or aluminum, material to match your tank. Our valve then bolts on to the flange of the installation tube.

Q) Is there a manual override for electric and air valves?
A) Yes there is, for the top control valves, just pull 2 pins remove the electric actuator or air cylinder and replace handle, the destaco clamp is now locking the valve shut. The side control valve also has a manual override, however the destaco locking system has to be removed for cylinder and actuator operation. If you need to release or remove the automation, pull safety override pin and manually tie your valve control handle.

Q) I have an old valve and want to upgrade to either stainless or new style 1050 series valve, will the valve fit into my opening?
A) Yes, our bolt pattern has never changed on our valve.

Q) What is the overall length of the valve with a telescoping chute?
A) The length on a standard 24” valve is a total of 60” when #4036 is fully extended from where the valve mounts to the tank. As a rule of thumb, if we cut off 1” on the valve length you will lose 2” additional off the length of the telescoping chute, 20” valve with #4036-54 would be 48” when extended, and 16” valve with a 4036-54 would extend 36” from tank.

Q) I have a compartment; do you build special length valves?
A) Yes we can move the controls further away from the tank, a minimum of 4”, and build the valve longer. Request a specification sheet, available for either top control or side control.

Q) I have a side control valve and it is hard to hold open, what can I do?
A) The Newton Valve is designed to hold open for the fastest dumping. However we do offer a lock open. Part #105070, can be purchased either as original equipment or added to your existing valve. We also offer a Telescoping handle on side control valves part #106016-1 which gives you better leverage. This also can be purchased as original equipment or added to your existing valve.

Q) What can I do if my valve leaks?
A) The first thing to check for is any rust or debris in your tank, not allowing the neoprene to seal up against rim of the valve. Check if your neoprene is cut or damaged. Check if your bearing is damaged. Always lock valve shut when your tanker is empty. Failure to do this will result in damage to the bearing. Do not allow the valve to slam shut, as this can also cause damage to the neoprene.

If your valve is a 1010 style:
A) After checking as suggested above. The bearing is slotted and can be raised or lowered to increase tension on the neoprene seal. Also you can give the piston a half turn. If you still have leakage call for technical assistance.

If your valve is a 1050 style:
A) After checking as suggested above. The bearing is slotted and can be moved to the left or right to increase tension on the neoprene seal. Tighten or loosen ¼-20 nylon locknuts, do not over tighten and bend plates. The brass is slotted and must slide freely. If you still have leakage call for technical assistance.
