Stainless Steel Needle Valve

Product Details:

A Stainless Steel 304 Bar Stock Ball Valve is a high-quality valve machined directly from a solid stainless steel block (bar stock) rather than being cast or forged. This manufacturing method provides superior strength, durability, and precision, making it ideal for critical and high-pressure applications.

• Machined from a solid SS 304 bar (not cast or forged)

• Compact, reliable, and precise valve design

• Provides bubble-tight shutoff with a spherical ball element

• Suitable for fluids, gases, and steam

• Superior mechanical strength and fatigue resistance

• No casting defects (e.g., porosity, inclusions)

• Excellent corrosion resistance

• High dimensional accuracy and tighter tolerances

• Longer service life in demanding environments

• Chemical processing

• Pharmaceutical industry

• Oil & gas

• Food & beverage

• High-purity water systems

• Instrumentation and analytical systems

An SS 316 Needle Valve is a precision control valve made from Stainless Steel 316, used to accurately regulate or shut off fluid flow in high-pressure, high-temperature, or corrosive environments. Its name comes from the needle-like plunger that fits into a small seat, allowing fine control of flow.

• Corrosion resistance: Superior to SS 304, especially in chloride-rich or acidic environments

• Applications: Chemical, petrochemical, marine, pharmaceuticals, water treatment, food processing

Needle Valve – SS316, 1/4" NPT Female x Female, 6000 psi, Bar Handle, Metal Seat, Straight Pattern, Lockable Stem

• Instrumentation lines

A SS 304 Panel Mount Ball Valve is a compact, manually operated valve designed for mounting through a panel or control enclosure. Made from 304 stainless steel, it offers excellent corrosion resistance, durability, and performance in a wide range of applications.

• Material: 304 Stainless Steel (SS 304) – durable and corrosion-resistant

• Mounting Type: Panel mount – designed to be secured from the front side of a panel using a lock nut or mounting plate

• Valve Type: 2-way or 3-way ball valve (specify as needed)

• Thread Type: Usually NPT, BSP, or compression fittings

• Operation: Manual lever handle for quarter-turn on/off control

• Seal Material: Often PTFE or Viton, depending on application needs

• Working Pressure: Varies by design (commonly up to 1000 PSI or more)

• Temperature Range: Typically -20°C to 180°C (varies by seat material)

• Control panels for pneumatic or hydraulic systems

• Chemical processing equipment

• Laboratory and instrumentation setups

• Water treatment systems

• Food and beverage machinery (non-sanitary grade)

• Threaded or smooth stem with lock nut for securing to the panel

• Flat face behind the handle for flush or semi-flush mounting

• Handle remains accessible on the operator side of the panel

A Stainless Steel Needle Valve Male × Female (M × F) is a compact, high-precision valve used for flow regulation or shut-off in fluid and gas systems. The male inlet and female outlet threading (or vice versa) allows direct inline installation without additional adapters, making it ideal for space-constrained setups or when connecting to existing female or male-threaded components.

• Precise flow control using a fine-threaded stem

• Compact Male × Female connection saves space and fittings

• Suitable for high-pressure instrumentation and isolation points

• Ideal for gases, steam, hydraulic oil, chemicals, and water

• Leak-tight, blow-out-proof stem design ensures safety

• Optionally available with locking handle or panel mount design

• Pressure gauge isolation

• Instrument calibration points

• Sampling and vent lines

• Chemical injection systems

• Steam and condensate drain valves

• Skid-mounted control systems
