The Haskel?54416-4 is a stainless steel, 2-way normally open air pilot (pilot-operated release) valve rated for 25,000?psi in high-pressure systems. With a 300:1 area ratio, it ensures consistent unlocking at low pilot pressures (~83?psi) and minimal internal leakage. Ideal for automating pressure relief and system shutdown in high-pressure pumps, boosters, and gas systems. Compact (approx. 3 " L 1?" ) and lightweight (~1?lb), it fits seamlessly within maintenance and safety setups.
