3-Series Bleed-down Valve Body 1-18311 Water Jet Pump Parts

The 3-Series Bleed-Down Valve Body 1-18311 is a critical structural component used in the bleed-down valve system of 3-Series Waterjet Intensifier pumps. Its main function is to house and support the internal valve components responsible for safely releasing trapped ultra-high-pressure water during system shutdown and maintenance.
This valve body works together with seals, springs, poppets, and related bleed-down valve parts to ensure controlled pressure discharge, stable valve operation, and reliable sealing performance. It is precision machined to withstand extreme pressure conditions while maintaining accurate alignment and safe operation.
A high-quality bleed-down valve body is essential for maintaining system safety, reliable pressure release, and long-term pump stability.

Is 3-Series Bleed-Down Valve Body 1-18311 a Wear Part?

Yes — the 3-Series Bleed-Down Valve Body 1-18311 is considered a semi-wear part.
Although it is more durable than internal sealing components, it continuously operates under ultra-high pressure, water impact, vibration, and repeated maintenance cycles. Over time, it may experience thread wear, sealing surface damage, corrosion, cracking, or internal erosion.
If not replaced when damaged, it can cause leakage, unsafe pressure release, unstable valve performance, and reduced system reliability.
Regular inspection during maintenance is strongly recommended.
