Selectable valve and valve unit
A selectable valve (4A) according to an embodiment includes a valve block (5) and a valve body (52) located in a valve body hole (51) of the valve block (5). The valve block (5) includes a first discharge port (9a) on a first engagement surface (5a) and a second discharge port (9b) on a second engagement surface (5b). Furthermore, the selectable valve (4A) is provided with: a bonnet (61) which is attached to the valve block (5) and which forms a pressure receiving chamber (53) facing one end surface of the valve body (52); and an electromagnetic proportional valve (7A) that is attached to the bonnet (61) and outputs secondary pressure to the pressure receiving chamber (53). A discharge passage (9) is formed in the valve block (5) and the bonnet (61) from the first discharge port (9a) to the second discharge port (9b) via the electromagnetic proportional valve (7A).
根据一实施方式的可选阀(4A)包括阀块(5)和位于阀块(5)的阀芯孔(51)内的阀芯(52)。阀块(5)包括第一接合面(5a)上的第一排放端口(9a)和第二接合面(5b)上的第二排放端口(9b)。此外，可选阀(4A)包括：阀盖(61)，其安装于阀块(5)、且形成与阀芯(52)的一端面面对的受压室(53)；和电磁比例阀(7A)，其安装于阀盖(61)、并向受压室(53)输出二次压。阀块(5)及阀盖(61)上形成有从第一排放端口(9a)经由电磁比例阀(7A)至第二排放端口(9b)的排放通路(9)。
