danfoss safety valve free sample
With the SFA 10 and DSV 10 change-over valve, Danfoss is widening its range of highly reliable safety valves designed to industrial standards. The new safety valves with their lower capacity and higher pressure range up to 65 bar provide more flexibility in system design. The SFA 10 can now be used in C02 applications on the low-pressure site as well as in low-charge ammonia systems. Furthermore, the spring housing is designed for reliability, increased lifetime, and to have no sudden reliefs below set pressure.
The priority valve OLSP 80 is to be used in connection with e.g. Danfoss gear pumps type SNP. As well as, steering units type OSPC LS, OSPF LS, OSPD LS and OSPQ LS in load sensing steering systems. There maximum oil flow doesn’t exceed 80 l/min. OLSP priority valves are to be flanged on gear pumps with outlet ports square flange type 35. Versions Load sensing static priority valves Load sensing static steering units require load sensing static priority valves. Load sensing static steering systems have no oil flow in the LS connection. This is when the steering unit is in neutral position. Load sensing dynamic priority valves Load sensing dynamic steering units require load sensing dynamic priority valves. Load sensing dynamic steering systems have a constant oil flow in the LS connection from the priority valve to the steering unit. Even when the steering unit is in neutral position.

The safety function is a feature of the actuators, which is mandatory by law or customer requirement, to close or open the valve in case of a power failure. It often happens that the power is out and the valve is therefore not under control anymore. This could lead to catastrophic consequences for the application/industry and most importantly for the safety of everyone in the vicinity of the valve as it can have more than 130°C of pressurized water in the system.
The safety function enables you to close or open the valve automatically (via the spring inside the actuator) each and every time the power goes out. SD means spring down, which will move the actuator to lowest end position, SU means spring up which will move the actuator to highest end position. You can find both versions in the Danfoss portfolio.
We recommend that you choose Danfoss AME actuators with BLDC motors technology as they have speed selection possibility on DIP switch. For example AME 655/658/659 actuators can move at either 2 s/mm or 6 s/mm, depending on the setting on the DIP switch. To check which actuators have selectable speed, please contact our sales organization.
It often happens that the actuator has larger stroke than the valve. Danfoss actuators have a self-commissioning protocol where they find the end positions of the valve on which they are mounted automatically. The actuator remembers these positions itself and adapts its stroke to the valve. This is how a lot of time and trouble can be saved when installing / commissioning the actuator on the valve.
Yes, an adapter is needed for this combination due to a different design of valve neck for the range DN 65-80. The needed adapter for the actuator to be able to be mounted on the valve is 065Z0312.
It is compliant with all current legislations and safety standards, including the Machinery Directive, and not only improves your design flexibility and product development, but also ensures a repeatable high performance and precision because of its maximum compatibility with proven technology.

Every once in a while I have to confront an opinion that Multi-Function valves from Danfoss series 90 closed-loop pumps are "all the same". There is a big chance that this myth is a local Portuguese phenomenon that emerged due to the lack of technical curiosity on the part of certain dealers, who traditionally give more attention to the commercial side than to the technical details of the product they sell and promote. In this article, I will explain, yet again, the function and principle of operation of these valves, as well as the difference in the dynamic behavior between their types.
The check valve function allows the charge oil to enter the low-pressure side of the loop. The function is performed by the two-piece poppet located in the nose. (cutaway view). The outer ring lifts the smaller poppet from its seat and lets the charge flow fill the loop. This assembly functions as a logic element check valve configured for annulus flow (free flow from side to bottom).
The by-pass function inter-connects the loop legs when necessary (for emergency towing, for example), and is activated by loosening the middle hexagonal actuator (which, by the way, has a very "thin-ish" design, in my opinion. I"d make the hex at least 5 mm thicker). This loosens the pre-load of the pressure spring and thus turns the assembly into an open relief valve, which will return to its original setting when the hex is re-tightened. Not a by-pass by-pass, per se, but it does the job, I guess.
And finally - the pressure relief function, which cuts through the fast pressure surges by venting the high pressure into the low-pressure leg of the loop when the limiter function isn"t fast enough. The inner part of the two-piece poppet (the outer part provides the check valve function, the assembly would work with a single-piece poppet, but the two-piece design makes the relief poppet much lighter and therefore increases its opening speed) acts as a logic element piloted by the pressure limiter poppet.
It is the latter two functions - the limiter and the cross-port relief - that have different behavior according to the type of a multifunction valve. The visible difference between the three types that you see in the pictures below is the diameter of the orifice in the nose poppet, and, obviously, the numbers stamped on the side:
The official catalog states that the relief function of a multi-function valve is sequenced to operate at approximately 35 bar above the pressure limiter setting and that the relief response time is approximately 20 ms. The keyword is "approximately". The actual values will depend on how fast a pressure surge is, which will be determined by the system design and operating conditions. However, if we tested the three types (type 1, 5, and 2) of the multi-function valves under the same surge rate, we would obtain different results:
Under repeating conditions, the type 2 valve would spend more time cross-porting, thus causing the oil to heat more, but also keeping the pressure surges at a lower level if we compared it with the type 1, for example, which would provide a faster limiter function, at the expense of higher pressure spikes.
The correct choice of a multi-function valve is determined by the system it is used in, so special care should be taken when replacing damaged valves. By saying "special care" I do not mean that it is imperative to replace a broken multi-function valve with the same type. What I mean is - common sense - i.e realizing what will alter if the valve type is changed, and then seeing if it"s acceptable.
The reason I am putting only the types 1, 2, and 5 here is simple - these three are the only ones I"ve seen pass through our shop. According to the Danfoss parts list for series 90 there are more.
The multi-function valves for series 90 have a simple and compact design, and as a rule last as long as the pump itself. I have seen them shatter and cause a catastrophic pump failure, but it"s not an everyday malfunction. If I could change one thing about these valves - it would definitely be the hexagonal adjusters! I would make them taller and therefore easier to clamp a standard wrench on.
