Description

Manual needle valves

Needle valves offer maximum safety and reliability in handling flow, even in harsh operating conditions. These valves can be used bidirectionally and effectively isolate both liquids and gases. The heart of the valve is the specially shaped seat and the two-piece non-rotating stem. The longevity and reliability of these valves are ensured because the stem cannot lock against the seat. The pressure-containing parts are made of high-quality corrosion-resistant stainless steel. Reliability is documented through traceability, as each valve body includes references to trace its origin in case of issues. Medium-pressure (MP) and high-pressure (HP) valves come complete with collars and glands.

 

Actuated needle valves

High-pressure circuits can be automated using pneumatic actuated needle valves. The valve bodies and sealing system are identical to those of manual needle valves and offer the same advantages.

Actuated needle valves are available in the following versions: NC (normally closed), NO (normally open), and DA (double-acting).

All the brands we distribute use different materials for the needles compared to standard valves for valves designed for use with hydrogen. 

In particular, PHP uses SUH660 material for its needles. SUH660 is a type of material composed of 25% Ni. A high Ni content helps to mitigate hydrogen embrittlement.

The remaining part of the needle valves is made of AISI 316, except for the actuator, which is made of aluminum.

There is also a pneumatic actuated version available. The actuators are made of aluminum and comply with ATEX directive.

Ball valves come in two types of connections: NPT and MP/HP coned and threaded. Additionally, this type of valve is available with electric or pneumatic actuators.

The available materials include:

  • Body/Side Adapter/Trunnion: Cold-316 cold worked stainless steel.
  • Packing: O-ring with PEEK backup ring.
  • Seals: Viton
  • Bearings: PEEK

The ball valves are made with end connections of 1/4, 3/8, 9/16, or 3/4 MP. The stem design and ball construction using trunnion technology ensure perfect alignment and sealing of gaskets.

These types of valves use high-durability sealing gaskets that have been tested up to 100.000 on/off cycles without leaks. The dynamic stem sealing is ensured by a double O-ring seal with special reinforcement rings.

PHP can assemble the valve with very tight tolerances so that the seals can seat under pressure.

Series and gaskets for low temperatures down to -40°C, and bearings made of PEEK.

Valves can be provided with NORSOK M-710 certification.
