A fast-actuating on-off valve and pressure regulator particularly well-suited for use with high-pressure incompressible fluids. An actuator, manually-operated or powered, provides a linear push-pull force to a valve stem assembly mounted inside a valve cavity having a fluid inlet and one or more fluid outlets. The valve stem assembly includes a valve stem that has a shoulder at one end. The valve stem assembly includes a stem collar having a capped end with a central hole to engage the valve stem, a cylindrical cavity to house the stem shoulder, and a threaded portion engageable with a valve poppet or a poppet extension. Each valve poppet has a threaded end engageable with the stem collar and a sealing end to engage with a fluid outlet centrally positioned within a valve seat or a valve poppet. The end of the valve stem which is opposite the shoulder end extends beyond or outside of the valve body, preferably through a stem seal and a seal support, and into a valve stem anchor for engaging a power piston of an actuator or a valve trigger of a manually-operated actuator.
