Описание

Гидравлическое оборудование, работающее на энергии жидкости, используется практически во всех отраслях промышленности и строительства. Клапан R900407439 и другие системы из ассортимента, созданные ведущими производителями, являются эталонами в своем классе и рассчитаны на большие нагрузки. Модели разработаны для интенсивной работы в широком температурном диапазоне и не нуждаются в частом ремонте.

Их отличные характеристики, надежность и безопасность подтверждают сертификаты, а так же декларации качества и соответствия.

The isolator valve type Z2S is a releasable check valve in sandwich plate design.

It is used for the leakage-free blocking of one or two actuator ports, also in case of longer standstill times.

In direction A① to A② or B① to B②, there is a free flow; in the opposite direction, the flow is blocked.

If, for example, there is a flow through the valve in direction A① to A②, the control spool (1) is moved in the direction of the B side, opens the ball seat valve (2) and then pushes the poppet (3) off its seat. Hydraulic fluid can now flow from B➁ to B➀.

In order to allow the ball seat valve (2) to be safely closed, the control spool (1) must be hydraulically unloaded (see circuit example).

Pre-opening

Due to the pre-opening, there is a damped decompression of the pressurized liquid. Thus, possible switching shocks are avoided. ▪ The two-stage set-up with an increased control open ratio means even low pilot pressure can be unloaded securely. ▪

Type Z2S 10 ‒… (with pre-opening)

Type Z2S 10 A…

Type Z2S 10 A…SO40

Type Z2S 10 A…SO60

Type Z2S 10 ‒…SO41 (without pre-opening)

Type Z2S 10 ‒…SO14

Circuit example, schematic

1	Control spool, area A₂
2	Ball, area A₃
4	Poppet, area A₁
5	Stop
6	Control spool, area A₄

①	component side
②	plate side

Notice:

In valves without pre-opening, sudden unloading of pent-up pressure volume may occur. Resulting switching shocks may lead to premature wear on installed components, as well as noise formation.

Notice:

Deviating from ISO 4401, port T is called TA, port T1 is called TB.

Important information on hydraulic fluids: For more information and data on the use of other hydraulicfluids, please refer to the data sheets above or contact us. ▪ There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). ▪ The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. ▪ Flame-resistant – containing water: ▪ Maximum pressure differential per control edge 50 bar ‐ Pressure pre-loading at the tank port > 20 % of the pressure differential, otherwise increased cavitation ‐ Life cycle as compared to operation with mineral oil HL, HLP 50 … 100%. ‐

Notice:

Selection of optimal sealing material (see "Type code") also depends on the type of hydraulic fluid used.
