|Can a three-way Ball Valve be used in a center-off position?||Yes, but there is no firm center-off position. One has to rely on sight or leakage to assure proper positioning.|
|What valves have vented-to-atmosphere options?||Currently, only the MB Series Ball Valve and the PR Series Plug Valve have this option.|
|Why are the pressures limited in vent-to-atmosphere valves?||Pressures are limited primarily for the protection of individuals at or near the valve.|
|Is the Hi-Pro range sub-sea qualified?||No|
|Parker's fire safe certification for Hi Pro is to BS6755-2. Do we have certification to API-607?||When Parker conducted fire testing on our valves BS6755-2 was the required standard, compliance to this standard also gave automatic compliance to API 607 as the standards were identical. So Parker can say we have compliance to API607. Our fires test is in accordance with API STD 607/API 6FA|
|Do Parker supply jacketed ball valves?||No, only standard Hi-Pro. A customer would have to supply their own jacket.|
|Are any of our Ball valves UL / FM approved?||No, we do not hold these approvals.|
|Are Parker instrumentation ball valves suitable for use with steam?||No|
|Can Parker perform a pressure test on Hi-Pro ball valves?||Parker Hi-Pro Ball Valves are pressure tested. The customer can request a pressure test certificate required.There is a small cost associated with this which is price listed and testing must be requested at time of order.|
|Can we have a ball valve repair kit?||No, ball valves are not user serviceable.|
|The customer wants to change the end adapter to convert the connection to a different type. Can they?||No, they are not user-serviceable. The customer can either return the valve for retro-fitting, or we can supply an adapter fitting. If the customer has already removed the end adapter, then they really need to send it back so we can fit a new one.|
|Is the B series ball valve available in 6Mo?||Yes|
|Is the MB series ball valve available in 6Mo?||No|
|What is the longest length of sampling probe/quill we can do?||750 mm|
|Can we confirm that soft seated Hi-Pro valves can pass both the through body and external leakage requirements of API607?||Yes, Hi-Pro can do this.|
|Are Hi-Pro ball valve handles capable of withstanding direct exposure to fire without becoming inoperable, as per API607?||The Hi-Pro Ball Valve handles are stainless steel and capable of direct exposure. The valve will be operable as described by API607.|
|Is a spanner supplied with spanner actuated valves?||No|
|Can we have ball-ball-ball on anything other than a 10mm ProBloc?||No, this arrangement is only available on the 10mm range, and not at all on FE versions.|
|Is the Hi-Pro range available in dual-certified 316/316L? Is the B-Series?||The Hi-Pro Ball Valve range is, the B-Series Ball Valve isn't|
|Can we supply ball valves with car seals?||Car seals are a simple wire lock device used to lock or 'seal' a valve in the open or closed position to prevent unauthorized operation of the valve. Valve operation can only take place by cutting the seal, thereby giving evidence of either tampering, or activity by an authorized worker. We can supply handle locking ball valves that can be used with car seals.|
|Can we do oxy clean on Hi-Pro ball valves?||No. A decision was made that the internal cavities can't be cleaned properly enough.|
|Can Hi-Pro ball valves be used for gas service?||Yes, but not recommended for compressed natural gas (CNG)|
|Why is PEEK rated to 6000 psi (CWP) in a B series ball valve but PTFE only rated to 1500 psi?||When IPD developed their range of valves, there were no international standards for them to follow. Thus they developed a range of products with detailed product testing and published a range of maximum working pressures (this was in the 1960's & 70's.
In the 1990's a new standard was released as a design standard for Instrument Valves - MSS SP-99. IPD decided to adopt this standard for their product range. This required a whole range of additional product verification testing as a result all of our catalogues were changed to add the terminology CWP. Where you see this reference against pressures it means that this is the cold working pressure in accordance with MSS SP-99. Unfortunately, one valve range - the B series - resulted in a lower CWP than our originally developed pressure rating.
The CWP is based on a 4:1 factor of safety, along with some other calculations related to material strength.
The B-Series Ball Valve was designed to have a pressure rating of 6000 psi across the whole size range. Many customers still use them for 6000 psi. However, the B6 has a CWP of 4400 psi & the B8 4000 psi. This is the reason for the numerous pressure statements in our catalogue. So if your customer needs 4:1 pressure rating then they should work around the lower pressures (4400/4000). If you customer does not need 4:1 then they can use the higher pressures (6000).
Finally, we offer three different seat materials - PTFE; PCTFE & PEEK. Both PCTFE & PEEK offer full CWP / Pressure rating capability. PTFE however, is a much softer material and in this valve design has it's pressure rating reduced to 1500 psi
|Why can't Parker do 1" class 25mm ProBlocs?||The reason is that the bore is obviously a larger diameter, while the flange bolt holes remain the same. We need to leave clearance on the OD of the ProBloc for a spanner to be able to tighten the bolts, and so in turn the ProBloc bodies outside diameter must remain the same.
There comes a point where the material wall thickness between the bore and the outside diameter of the flange becomes too thin, and this happens with the 1" bore ProBlocs. On larger sizes the bolt hole PCD is also bigger, and so we don't have this issue.
|What is the materials of the ball, needle and stem? Is it A182-F316||They are ASTM A479 316 Stainless steel, made from cold rolled bar.|
|Is the graphite packing material flexible and with corrosion inhibitor?||Yes, it is flexible graphite with corrosion inhibitor|
|Does Hi-Pro conform to API 6A?||No, the wall thicknesses are insufficient.|
|Does Hi-Pro conform to API 6D?||API 6D only applies to valves of size 2" and above, so is not applicable to Hi-Pro Ball Valve
|On a B-series ball valve, what does the 'S' mean near the start of the part number? For example, M16AS-B8LPKR-VM-SSP-R110?||It means that it is approved for CNG use to ECR110 (hence the 'r110' at the end of the part number which should also be there.|
|What does an 'H' suffix mean at the end of a b-series ball valve?||The -H indicates heat code traceability for the B-Series Ball Valve and is required if the customer requests material test reports for the valve. |
|What is the minimum temperature a ProBloc can go to? What is survival temperature?||-70C for blow down only. This is survival temperature only.|
|Are the padlock holes for handle locking the same diameter on manifolds and needle valves, as for ball valves?||Yes, they are all standardized at 6mm diameter.|
|202D-0596- is this in blue or black?||202D-0596 comes in blue. We don't have an option for a black handle for these valves.|
|A 'LB' series ball valve I want is obsolete. What is an alternative?||We would suggest a B-Series Ball Valve|
|How many cycles per second can a ball valve open-close?||As our ball valves are not intended to be used this way, we do not have this information.|
|We are looking for electronic actuators for 4 way valves, specifically for 2A7-MB6X4PFA-SSP. In the information about electronic actuators for MB series Valves, the 4 ways are not mentioned at all. However, this particular calve only rotates 90 degrees, so would it work with for instance the 80 Series electronic actuator?||Any of the electric actuator series can be used this way on the MB6X4|
